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.

Inventory Lab

  • InventoryLab is no longer sold standalone and is now bundled into Three Colts' Seller 365 plans starting at $69 per month for a single user, rising to $199 per month for the Pro tier
  • Multichannel listing requires the separate UniCon add-on, priced from $49 to $449 per month depending on tier
