Hey - dumb question that is probably a derail: Is there a practical reason in the US to use Instacart over one of the Amazon services? It seems like they are fighting an uphill battle - Amazon has its own grocery warehouses (Prime food), and owns Whole foods. I haven't cross-shopped recently, but am having a hard time imagining them competing on price with either of those services. I suppose the obvious reason is you aren't limited to those two stores, so if you want specialty items, nice baked goods etc you would use Instacart?
They do compete on price. Amazon charges for Prime, charges extra for delivery, and Whole Foods is generally among the most expensive grocery stores. Instacart offers a ton of cheap alternatives.
Instacart delivers for costco
Yeah instacart isn't limited to specific stores, you can even order from multiple stores and group them
Instacart is also integrated with several stores. Kroger and Costco both use Instacart for their pickup and delivery services in their own apps.
