I used to shop on instacart but the lack of transparency made me switch back to going-to-the-store shopping. Started using prime now for about 2 months and love how much more transparent it is about its costs. They charge the same as the store and add a default $5 tip as suggested tip. Wish instacart would get their shit together. Delivery business is a growing market and would love to have multiple great providers. Also feel for instacart since it was so much early to the game than all of its current competitors.
