Vouchers 7% Tesco Clubcard Points @ B&Q

You can buy £25 B&Q Gift Cards at Tesco, and on page 120 of the Tesco Xmas magazine there is a voucher to get 100 extra Clubcard Points when you buy a £20 or more gift card. http://www.tesco.com/giftcard/branded-gift-cards.asp

The B&Q vouchers are in denominations of £25, so if getting 2 of them in one transaction with 2 vouchers you'd be getting an extra 200 Clubcard Points + the 150 points mentioned in the above link for buying £50's worth of gift cards.

That's 7% Clubcard Points on your B&Q spend, far better than what you get at Tesco. Might also be worth having a look at the gift cards for other stores.
