Mediocre app! The replacement options refresh to "shoppers choice" instead of the previously selected options whenever you make an item search. I never get notifications unless my phone is unlocked and the app is open. Also, there is no way for me to make a note saying that I can't receive orders before a certain time which lead to my husband and I rushing home from work before the end of the day so our shopper wasn't waiting 30+ minutes in my driveway when the order was for 1+ hour later!
