Hubby will go grocery shopping for me

I am currently on a bed rest. I cannot go out of the house for a week and a half. My hubby and brother are doing pretty well in doing the chores around the house. Today or tomorrow hubby must buy the groceries, I should not forget to remind him to check the supermarket’s daily deals before he buy the stuff he needs to buy. Knowing him, he will just buy what’s on the list and not compare prices.
