yeah I use both sainsbury's and tesco's I find sainsbury's is better just because I don't have a problem with teh date issues. When I have ordered from tesco's I always have to check everything before I sign it off, as I ALWAYS get loads of things that have a really short shelf life...but with sainsbury's it never happens...any anything that is short is put into a separate bag and you are made aware of it. Tesco's hides it. But what I do is I use a website called.... mysupermarket.com and they are great. You just input all your items and it tells you whether tesco's, sainsbury's, asda, or waitrose (depending on your area) is cheapest. Plus they also tell you, that is you save X amount if you switch certain products and it shows you. Also it has the list of the fat,salt and sugar contents, and tells you, you will save X amount of calories etc if you make a switch to X. It saves me loads...plus you can acutally see the products properly. I couldn't tell you the times I have bought something thinking it was one size and get it and it is either bigger or smaller than I thought. But check it out next time you shop. I think I have saved about £60 this month using it.
