I sometimes collect receipts which have been left at tills in Tesco or Sainsbury’s and if they haven’t used a loyalty card, I add the points to mine. I was googling to find out if this is actually legal, and found that it seems to be okay as long as you don’t ferret around in the rubbish bins for them.
I was amused to learn that this is known as Wombling, which I suppose is fairly self explanatory.
Does anyone else do this? Sometimes it can be a lot of points! Or money off or something.
