Hello! I've wrote a post about Shopmium:

Join up, for free, using code
KMHMUEAV and get yourself a free item. At present it is a box of ice creams.
You buy the item, scan it, and your receipt, and then you get yourself some cash back.
Sometimes items are free, other times you get a discount. They have new offers really regularly and for a variety of supermarkets including Tesco, Asda, Morrisons, Waitrose, Sainsbury's and even the Co-Op!
