Not sure on frozen or items needing refrigeration. – Pick 'n Save Review

Do to a recent accident I’m forced to use a delivery service for groceries. The online ordering was self explanatory, but the only thing that is unknown is how long would items that need refrigeration or the freezer be left out once the order is placed? This needs needs to be addressed & shared with customers. I wanted to order ice cream & other frozen items but do the order pockets pull those items first then shop for remaining items? Do the groceries sit for an hour before a delivery service delivers? Please address my concerns.
