I have seen these machines in a few of the bigger supermarkets, although not in our smaller ones out in the sticks. I noticed it was 7p in the pound they charge, but thought the supermarket was getting the money, so its better if it is a charity.
I have never used these machines, but am I right in thinking it pays out tokens which you take to the customer services? And do they actually give you the cash, or is it a gift card to spend in their store I wonder?
