I was in Tescos yesterday and noticed that they are stocking Ryvita Goodness Bars ( 3 different flavours). You get 6 in a pack and the front of the box had a blue sticker saying that if you go onto http://www.ryvitarewards.com
, enter the code that appears on the inside of the box, you get £1.89 back. I've done it and got an email saying that the cheque should reach me within 30 days.
Best bit is Tesco are currently selling the bars at 99p so you make 90p profit!!!!
