Don't grumble, but I really can't figures out these tesco clubcards.
I have had one for a while. What I want to know is- when they send your statement with the voucher to spend off food, if you want to, if I don't use it have I lost that voucher/money off for good? Or do you just not use them and let them accumlate and is that how you save and change them for airmiles? I know you can get airmiles but I don't know how?
Thanks any help will be appreciated
- and yes I have looked at the web site, but I must be missing it if it actually says what I want to know.

Thanks any help will be appreciated
