How Mercari Shipping Works

Mercari offers two shipping options for sellers:

  1. Mercari Prepaid Shipping Labels (most common)

  2. Shipping on your own (optional)

📨 Mercari Prepaid Labels

When you list an item, you can select:

  • Weight and size of the package

  • Preferred carrier (USPS, UPS, FedEx)

Mercari then generates a discounted prepaid shipping label for you to print. This is usually cheaper than retail shipping rates.

Shipping on Your Own

Advanced sellers sometimes use their own labels if:

  • They get better rates through third-party carriers.

  • They want more control over shipping methods.

  • They are bundling multiple items.

⚠️ If you self-ship, make sure to upload tracking manually and ship within 3 business days to stay compliant with Mercari’s policies.

How to Save on Mercari Shipping Costs

Shipping doesn’t have to eat into your profit margin. Smart sellers use these tactics to keep costs low.

1. Use Accurate Weight

Overestimating weight leads to paying for a higher tier. Weigh your package after packing to ensure accuracy.

2. Keep Items Under 1 lb

Items shipped via USPS First Class (under 1 lb) are the cheapest to ship on Mercari.

3. Use Lightweight Packaging

Avoid unnecessary weight by using:

  • Poly mailers instead of boxes.

  • Small boxes for fragile items.

  • Recycled packaging where possible.

4. Bundle Sales Strategically

Bundle multiple small items into one shipment to save on per-item shipping costs.

5. Let the Buyer Pay Shipping

For some categories, buyers are willing to cover shipping. This protects your profit margins.
