thehatfox'Buy one, get one free' deals for unhealthy food banned in supermarkets
melsaskcaThat always bugged me. How about half-price?
If only, nowadays at most i see something like: buy 3 get 1 for free (only cheapest option is free, *conditions apply).
Always about moving quantity. People may grab just one unit at 50% off vs every purchase is required to buy two units minimum.
