£20 And thats with a voucher, this sort of practice of the supermarkets needs to be stamped out.
I agree- I read that the powers that be are looking at retail price practices, including "Buy one get one free".
Buy one get one free is a good deal when, for example, shops are clearing out stock , overstocked lines, end of season lines - Christmas cards in January, for example. IE when the item has been on sale , without a "freebie" at full price previously.
