I don't know what the BOGOF (offers) have to do with anything but here I also note the supermarkets deception.
For example a sign over some JACOBS CREAM CRACKERS:
CREAM CRACKERS BUY ONE GET ONE FREE
in huge letters, then is much smaller letters Betterbuy 200g.
Note you have to travel up the isle sometimes to the other end of the store before you find Betterbuy cream crackers, yet the sign is placed with the Jacobs cream crackers. On finding the Beterbuy brand you discover they are 150g and the offer applied to 200g. Morrisons is the worst offender for this, putting signs over the wrong product to encourage sales of not just one but 2 of the item and usually above the normal price. I've seen loads of people buy like this but I read things properly and I don't think many people do. Also on discovering the Beterbuy crackers and purchasing them at the check out they are likely to charge for 2 items, because you didn't notice the offer ends date was yesterday.. Signs like advertising use signs that appear to say one thing but mean something different entirely.. I've worked in advertising so I know all the tricks but it doesn't stop me thinking it's wrong to purposely try and decieve.
