Copy-ready counter

I can do the bundle at $67.92. That keeps the discount fair while covering combined shipping and platform fees.

Bundle rule checks

Checked 2026-08-08. Mercari supports buyer bundle requests from one seller with item and price constraints; Poshmark and Depop have native bundle flows, but fee basis and shipping discounts still need a seller floor.

What reseller job this solves

Use this when a buyer asks for multiple items or you want to clear slow movers without accidentally accepting a below-floor offer.

The calculator compares two decisions: wait for separate buyers, or move the items together at a discount. Shipping savings and higher bundle probability can make a discount rational, but only above the target-profit floor.

Edge cases to check before sending the offer

  • Mixed-size returns: one bad-fit item can make the whole bundle risky, so add a return-risk reserve when sizing is uncertain.
  • Platform price limits: high-value bundles may need a custom listing or a different platform flow.
  • No shipping savings: if the bundle is bulky or fragile, combined shipping may not fund a discount.
  • Fast singles: do not discount items that are already moving quickly unless the buyer is paying above your target floor.
