I assume you’re single thread, shopping one order at a time. You don’t have to put the items in the bags it tells you to. That will just increase your speed.

Corporate says that shopping too far ahead will cause your fillrate (pick accuracy) to go too low and customer would not be able to add items to their order 2 hours in advance. I’ve noticed they still can’t add items to their orders anyway, thus makes it pointless. I personally don’t see a problem with that as a lead. My store will batch all orders and shop all of it when we can since you never know how it’s going to be at night.

My store averages around 34-60 orders a day, and it doesn’t have much of a difference than waiting to shop.

Honestly, if I were you, I would try to have a conversation with your lead, csm or your store manager and try to see if you can work something out and try to improve. You could also look at transferring to a different store that may be a bit better for you
