I swore off shopping apps the first time I tried it a few years ago, because everything seemed to be marked up 30%. Sneaky way to hide the true delivery/convenience fees.
Anyway I tried out Shipt today and the experience was fantastic. Regular store pricing, plenty of time slots, $10 delivery fee, the shopper was courteous and didn't fuck anything up.
With a $15 tip, it works out to ~8% vig on a $300 grocery bill. 100% worth saving an hour+ of my time, nevermind the reduced exposure to covid. I might continue using this when it blows over.
