You list a top on Mercari in July with free shipping. It sells in November, and your payout is smaller than you planned, even though you changed nothing.
That is because of the Mercari shipping label prices update of October 19, 2026. Mercari changed prepaid label costs for USPS, UPS and FedEx, and applied them to every listing at once.
For many sellers, the change is quiet but real. A few cents here and a dollar there can wipe out the profit on low-priced items.
It is not all bad news, though. Some shipping labels got cheaper, Media Mail dropped, and card sellers can ship 1 oz envelopes free until January 4, 2027.
In this guide, you will learn:
- What changed, and why Mercari made the move
- Old vs new prices for every major carrier
- How buyer-paid and seller-paid shipping are hit differently
- Which carrier is cheapest at each weight now
- Simple steps to protect your profit
Every number here comes straight from Mercari’s own rate tables. So you can plan your next listing with real figures, not guesses.
The Mercari Shipping Update at a Glance

Why Mercari Raised Shipping Label Prices?
Mercari says shipping carriers update their rates every year. They cite inflation, higher operating costs and changing demand.
The fall timing is no accident. In October 2024, Mercari also raised label prices when carriers added holiday and peak-demand surcharges.
This is Mercari’s third shipping price change in 2026. It follows a Standard rate increase in January and a USPS fuel surcharge in May.
Mercari still claims its labels save sellers 53% on average versus retail carrier prices. That figure slipped from the 54% it claimed earlier this year.

What Changed: Old vs New Mercari Label Prices
Mercari uses two price levels. Best rate applies when your box is 1 cubic foot or smaller and its longest side is 22 inches or less.
Standard rate applies to bigger boxes. You unlock Best rates by entering your package size when you list.
The tables below compare the May 7, 2026 rates with the October 19, 2026 rates. Both come from Mercari’s own rate page.
USPS Ground Advantage
| Weight | Best Rate (Old → New) | Standard Rate (Old → New) |
|---|---|---|
| 0.25 lb | $4.91 → $5.39 | $5.49 → $6.49 |
| 0.5 lb | $5.66 → $5.99 | $5.99 → $7.49 |
| 0.75 lb | $6.73 → $7.39 | $6.99 → $8.49 |
| 1 lb | $7.48 → $7.99 | $7.59 → $8.99 |
| 2 lb | $12.83 → $13.09 | $13.49 → $14.99 |
| 5 lb | $14.97 → $15.99 | $16.99 → $18.99 |
| 10 lb | $20.32 → $21.99 | $21.99 → $23.99 |
Standard labels under 1 lb jumped $1.00 to $1.50. Best rate labels rose only 33¢ to 66¢.
That widens the gap between the two. At 0.5 lb, Best used to save you 33¢. Now it saves you $1.50.
UPS
| Weight | SurePost Best (Old → New) | Ground Best (Old → New) |
|---|---|---|
| 0.25 lb | $7.97 → $7.94 | $11.99 → $14.99 |
| 1 lb | $7.97 → $8.09 | $11.99 → $15.49 |
| 3 lb | $7.97 → $8.69 | $11.99 → $16.49 |
| 5 lb | $7.97 → $9.39 | $11.99 → $17.29 |
| 10 lb | Not offered | $11.99 → $18.49 |
UPS’s budget option (listed as Ground Saver in May, SurePost now) lost its flat $7.97 price. It now climbs by weight, from $7.94 to $9.39.
FedEx Home Best experienced the largest price increase among these services. Its rates increased by $5.00 to $9.50, depending on package weight.
UPS Ground Best also saw significant increases, reaching 54% at 10 lb.
FedEx
| Weight | Economy Best (Old → New) | Home Best (Old → New) | Home Standard (Old → New) |
|---|---|---|---|
| 0.25 lb | $7.97 → $7.94 | $15.99 → $20.99 | $25.00 → $22.99 |
| 5 lb | $7.97 → $9.39 | $15.99 → $23.39 | $25.00 → $24.99 |
| 6 lb | $11.99 → $10.49 | $15.99 → $23.69 | $25.00 → $25.49 |
| 8 lb | $11.99 → $11.49 | $15.99 → $24.49 | $26.00 → $26.99 |
| 10 lb | $11.99 → $12.49 | $15.99 → $25.49 | $28.00 → $28.99 |
Here is a surprise. FedEx Economy Best got cheaper at 6 to 8 lb, by up to $1.50.
FedEx Home Best rose $5.00 to $9.50. Oddly, light FedEx Home Standard labels fell by about $2.
Priority Mail, Heavy Boxes and Media Mail
Priority Mail Best rose $1.00 at 2 lb but dipped slightly at 6, 8, 9 and 10 lb. For example, 10 lb fell from $38.52 to $37.99.
Heavy boxes barely moved. A 50 lb UPS Ground or FedEx Home Best label went from $49.99 to $50.99, and 100 lb stayed at $120.
Media Mail got cheaper across the board. It now costs $4.47 for 1 lb (was $4.99), $5.22 for 2 lb (was $5.99) and $5.97 for 3 lb (was $6.99).
Existing Listings Changed on Day One
This is the detail most sellers miss. In past updates, Mercari gave existing listings a grace period.
In January 2026, existing listings waited until February 16. In 2025, they waited until March 10.
This time, new rates hit all new and existing listings on October 19. A seller-paid listing you posted in July now costs more to ship, with no action from you.
Buyer-Paid vs Seller-Paid Shipping: Who Feels the Increase?
The Mercari shipping label prices update covers both buyer-paid and seller-paid labels. But the cost lands in different places for each.
If You Offer Free (Seller-Paid) Shipping
You absorb the full increase. Mercari takes a 10% selling fee on the item price, and the label comes out of what is left.
Here is a $20 item in a 0.5 lb package with seller-paid shipping:
| Label | Label Cost | 10% Selling Fee | You Keep |
|---|---|---|---|
| Best rate, before Oct 19 | $5.66 | $2.00 | $12.34 |
| Best rate, now | $5.99 | $2.00 | $12.01 |
| Standard rate, now | $7.49 | $2.00 | $10.51 |
Skipping your package size now costs you $1.50 on this sale. That is 7.5% of the item price, gone.
If the Buyer Pays Shipping
The buyer pays the higher label price. But you still feel it in two quiet ways.
First, Mercari’s 10% selling fee applies to the item price plus buyer-paid shipping. Every extra $1.50 in shipping adds 15¢ to your fee.
Second, a higher total price can scare off buyers. Picture a $12 item with $7.49 shipping: shipping is now almost 40% of the buyer’s cost before fees.
Buyers also pay a 3.6% Buyer Protection fee on the item and shipping. So every shipping increase grows their checkout total a little more.
Not everything got worse, though. Several parts of Mercari shipping stayed exactly the same.
What Did Not Change?
These features work the same as before October 19:
Shipping Protection: Prepaid labels still cover up to $200 if a package is lost or damaged. First-Class Envelopes are covered up to $20.
Flat national pricing: One price ships to all 50 states. Your buyer’s location does not change your label cost.
Best rate size rule: Boxes up to 1 cubic foot, with a longest side of 22 inches or less, still qualify.
Underpaid label rules: Carriers charge for the larger of actual weight or dimensional (DIM) weight. DIM weight is a price based on how much space your box takes up.
Underpaid penalty: If your package is heavier or bigger than your label, you pay the difference plus an 8% penalty.
Seller and buyer fees: The 10% selling fee and 3.6% Buyer Protection fee stay the same.
First-Class Envelope Promotions: Free and 49¢ Shipping
Mercari paired the price change with two deals for trading cards and paper collectibles. Both run through January 4, 2027.
| Envelope Weight | Promo Price | Regular Price After Jan 4, 2027 |
|---|---|---|
| 1 oz | $0.00 (free) | $0.74 |
| 2 oz | $0.49 | $1.03 |
| 3 oz | $0.49 | $1.32 |
How the Free 1 oz Deal Works?
The free label covers single trading cards and paper collectibles up to 1 oz. New listings could opt in from September 17 on app version 9.43.2-329644 or later.
Mercari opted in existing listings starting September 30. Still, open a few listings and confirm the promo shows. Terms apply.
Why This Matters More Than It Looks?
Free shipping makes $1 to $3 card singles worth listing again. After January 4, a 74¢ label eats a big slice of a $2 sale.
So the next eight weeks are your window. List low-value singles now and clear them before the promo ends.
Envelope Rules to Follow
1. Maximum size: 11½” long, 6⅛” tall and ¼” thick
2. Mercari limits these labels to eligible categories, mainly trading cards
3. Thicker or heavier packages need a regular package label
How This Fits Mercari’s 2026 Shipping Timeline?
The October update is one step in a busy year. Here is every Mercari shipping change in 2026, newest first.
| Date | What Happened |
|---|---|
| January 4, 2027 | Free 1 oz and 49¢ First-Class Envelope promos end |
| October 19, 2026 | New label prices hit all new and existing listings |
| September 30, 2026 | Existing listings opted into the free 1 oz envelope promo |
| September 17, 2026 | October price change announced; free 1 oz promo launched |
| May 7, 2026 | USPS 8% fuel surcharge added to Ground Advantage and Priority Mail labels |
| February 16 – April 16, 2026 | Promo: $4.99 UPS and FedEx labels for 1–5 lb |

Notice the pattern. Small USPS packages went up in May and again in October.
Also, Mercari has changed rates every January or February since at least 2022. Expect another update in early 2027, so plan your pricing with that in mind.
Seller Action Plan: 8 Ways to Protect Your Profit
1. Always Enter Your Package Size
This is the easiest money you will save all year. Under 1 lb, the Best rate now beats Standard by $1.00 to $1.50 per label.
2. Use a Smaller Box or Mailer
Keep packages under 1 cubic foot with a longest side of 22 inches or less. Poly mailers work well for clothing and soft goods.
3. Weigh After You Pack, Then Trim
Price tiers break at 0.25, 0.5, 0.75 and 1 lb. Dropping one tier can save real money.
For example, a 0.75 lb USPS Best label costs $7.39. Trim the box to 0.5 lb and it costs $5.99, a $1.40 saving.
4. Compare Carriers at Your Weight
The cheapest carrier changes with weight. Here are the new Best rates side by side:
| Weight | USPS Ground Advantage | UPS SurePost | FedEx Economy | Cheapest |
|---|---|---|---|---|
| 0.5 lb | $5.99 | $7.99 | $7.99 | USPS |
| 1 lb | $7.99 | $8.09 | $8.09 | USPS |
| 2 lb | $13.09 | $8.49 | $8.49 | UPS or FedEx |
| 5 lb | $15.99 | $9.39 | $9.39 | UPS or FedEx |
| 8 lb | $19.09 | Not offered | $11.49 | FedEx |
| 10 lb | $21.99 | Not offered | $12.49 | FedEx |
Under 1 lb, USPS wins. From 2 to 10 lb, UPS SurePost or FedEx Economy saves you $4 to $9 per label.
The trade-off is speed. Economy services can take a few extra days, so mention delivery times in your listing.
5. Switch Books and Media to Media Mail
Media Mail got cheaper, now $4.47 to $5.97 for 1 to 3 lb. Use it only for books, movies and recorded or printed music.
USPS can open Media Mail packages. If it finds ineligible items, you pay the extra cost and any fines.
6. Review Your Seller-Paid Listings
Older seller-paid listings now cost more to ship. Check your margins and raise the item price, or switch to buyer-paid shipping.
7. Push Bundles
One box with three items costs far less than three boxes. Offer bundle discounts so buyers add more to each order.
8. Weigh and Measure Every Time
An underpaid label means you pay the gap plus an 8% penalty. A cheap kitchen scale and a tape measure pay for themselves fast.
