Tesco Club card!

Me and DF have been using a club card for ages and been getting sent the vouchers in the post which we have just been dumping in a draw somewhere!
Ive finally realised how to use them (d'oh!) and just ordered us 3 tickets to take dd to chessington for her birthday for only £21.25 worth of Tesco voouchers! would of cost us about £70 otherwise! good eh! hehe!
