Here comes a no brainer:

Do you want to save money on your weekly shop? Up to 25% cashback on your shopping!!! At Tesco you earn a Β£1 voucher for every 100 points you earn and Morrisons you need to save 5000 points for a Β£5 voucher, which you have to spend in store!! This is CASH to spend anywhere on anything.

Make sense!?!?
