Excellent Scheme upto 4 x value in some circumstances

I love receiving my Tesco clubcard vouchers and working out how to get the most out of them. We had a lovely meal out at Ask recently where £10 in clubcard vouchers gave us £40 to spend on food in the restaurant. There are plenty of ways to make them go further too from Days out to gift purchases and Magazine subscriptions. Sometimes there are short term special offers, where the voucher goes further... last year we got a Thorpe Park ticket for £10 in clubcard vouchers.
The clubcard exchange scheme is also good. People complain about it but they are giving you double the value of your coupons. I would prefer if they let you double up from £2.50 but it's money for nothing isn't it? It is very clear on the Website and in store what you can and can't use the vouchers on so there is no excuse for people who complain they doubled up then couldn't use the vouchers on what they wanted.
I look forward to receiving my Tesco Clubcard statement each month :)
