big shop

A planned, regular shopping trip for groceries during which one buys many things. Primarily heard in UK, Australia. Luckily, we had already done our big shop for the week before the storm hit, so we were fine. I bet doing a big shop that you plan out each week would really help you to cut down on impulse buys. We need to do a big shop before your relatives come to town. Do you know what kinds of things they like to eat?
