Shop is an important word with different combinations to learn:
go shopping = a general phrase
do the shopping = when you buy things you need probably from the supermarkey
shop around = not buy the first thing you see but look for better value or the best product
purchase/make a purchase = a less common way of saying shop
types of shop
One question you might get is to talk about different types of shop. Here are some for you to think about. I have left out a lot of specialist shops:
a corner shop = a small, local shop that sells a little of everything – it needn’t be on a corner
a newsagents = a shop that sells newspapers
a chemist’s/pharmacy = a chemist’s is the British way of talking about a pharmacy or a shop that sells medicines
