What does 3 for 2 mean in shops?

Answer 1

Oh, dude, 3 for 2 means you buy three items, but only pay for two. It's like getting a freebie, but you still have to fork out some cash. So, it's basically a sneaky way for shops to make you buy more stuff than you actually need.

Answer 2

it means you can get three of the same item for the exact same price of two of that item

for example: if there were apples selling for 50 pence each instead of buying to for 1 pound you could buy 3 for 1 pound.
