Having tried (extensively) Instacart, Amazon WF and Freshdirect, Freshdirect is my absolute favorite. The fruit and vegetables are in stock, they're either almost ripe or just ripe, and there's a bunch of organic stuff. Instacart is hit or miss, the shoppers miss a third of the items and you feel guilty making them work harder. Also the constant alerts on the app that (50%+) items aren't available and to accept a substitution or a refund is a huge hassle when you're working and get interrupted once every 5 minutes about 15 to 20 times to make a decision. Amazon WF was the worst for me, items unavailable and the worst part is all the fruit and vegetables were so ripe as to be inedible almost immediately. I'm not sure what happened there. Amazon also screwed up because they were letting people put things in carts while no delivery was available, and auto magically removing items.
Back to the topic here. Fresh Direct has the most experience and has the best customer experience, so I really really hope they don't go out of business or get bought by Amazon!
