Cart Organization, best case practices when starting to shop a batch.
At the start of your batch prepare yourself for greatness by grabbing a bunch of produce bags. I try to start with about 8-15 produce bags depending on the size of your order. Time is money so you don't want to have to double back for them. If your just starting out and want to save time you can wait and bag them up while you wait in the check out line.
When shopping and placing items in the shopping cart I like to organize the products so that when I am at checkout I get the items on the belt the way I want them in the bag. As a rule of thumb you should always bag your own items however after the cashier is done ringing up your items they should be helping out with the bagging up of items.
