Instacart Delivery Interface

Instacart figured out that grocery shopping is one of those tasks where the friction isn't the buying but the remembering. Wait — actually, Instacart figured out that the real friction in grocery shopping isn't the buying but the remembering. A reorder button pulls from your last 3 orders so you do not have to browse every aisle again. The interface with Publix is cleaner than the one with Costco, probably because Publix gives Instacart better product photography and more consistent category data. The real design move is the replacement system. When something is out of stock the shopper suggests a swap and you approve it from a notification, and the whole exchange takes about 4 seconds on your end. That is a trust problem solved through interface design rather than policy. The delivery tracking screen shows the shopper's location on a map the way Uber does. Every logistics app has converged on the same blue dot moving along a gray road. It works, but it isn't original. The $4 delivery fee plus a service fee plus the tip makes the actual cost of convenience pretty visible. I appreciate that they do not hide it behind a subscription wall the way some competitors do.
