Tesco - Mega Desperado Idea

   If you were getting really desperate, you could collect all the receipts up the people leave in the bins near the tills at Tesco. Sift out all the ones where people haven't used their clubcard and then take those ones to the Customer Services. Tell them that you forgot your card on the day of purchase but that you'd like to claim your clubcard points now. Do this a few times and you'll have enough points to get a half decent shop.

   A bit desperate but when needs must!
