Where each one falls short

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

Instacart

  • Item prices shown in the app are frequently higher than the same items in the physical store, and this markup is not clearly separated from delivery and service fees at checkout, making true cost comparison difficult.
  • Shoppers are a mix of employees and independent contractors depending on market and retailer, and gig-classified shoppers have raised pay and working-condition complaints that have drawn regulatory attention in several US states.
  • The service fee and delivery fee combination means a small grocery order can carry a large proportional surcharge, making Instacart uneconomical for frequent small top-up shops.
  • Item substitutions chosen by a shopper when stock runs out can differ meaningfully from what was ordered, and refund handling for a poor substitution requires customer support intervention.
  • Availability is limited to the US and Canada, and even within those countries, delivery zones and retailer coverage vary block by block in a way that is not obvious until you enter an address.

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.
