Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mercari

  • The flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.
  • Shipping is the seller's responsibility to arrange and package correctly, and disputes over item condition or damage in transit are common friction points in buyer-seller resolution.
  • Instant payout carries its own fee on top of the selling and processing fees already deducted, so getting money out quickly costs more than waiting for standard transfer.
  • Buyer protection and authenticity verification are limited outside the specific luxury authentication programme, so counterfeit risk on unverified categories rests largely on buyer judgement of listing photos and seller ratings.
  • Market depth and typical sale prices vary significantly between the Japan and US versions of the app, and the two operate as largely separate marketplaces despite the shared brand.

Spree Commerce

  • Multi-vendor marketplace, B2B commerce and multi-tenant white label modules are Enterprise Edition only and licensed separately from the open source core
  • Enterprise Edition pricing is quoted per customer depending on modules and scale, with no published rate
  • Support with guaranteed response times and a success manager comes only with Enterprise Edition
  • The free Community Edition is self hosted, so hosting, upgrades and Ruby on Rails maintenance are the operator's responsibility

Mercari: Does the buyer pay any extra platform fee?

No separate platform fee is added at buyer checkout the way Vinted adds a buyer protection fee; the buyer pays the listed price plus shipping if not included.

Spree Commerce: What is Spree Commerce's pricing model?

Spree Commerce operates as free open-source software. Users self-host on their choice of infrastructure (AWS, GCP, Azure, or on-premise), so costs are based on the hosting infrastructure selected rather than platform subscription fees. An Enterprise Edition is available with optional dedicated support, but specific pricing is not published.

Source
Mercari: Is Mercari the same marketplace in Japan and the US?

No, they operate as separate marketplaces under the same brand, with different inventory, pricing and fee history.

Spree Commerce: Are there transaction fees with Spree Commerce?

No, Spree Commerce charges zero transaction fees. Unlike SaaS e-commerce platforms that take a percentage of sales, Spree offers predictable costs that don't scale with revenue, giving merchants full control over their margins.
