I have been giving them to the milkman for a few years now, but our nice old chap retired and we have a geezer who is not very regular, plus I find it hard to get the right amount of milk and usually end up with too little or too much, so I've told them I want to stop when my credit has run out.
I tried to use a milk token in Sainsburys the other day but it was refused as the min is £2.77 and if you buy 8-10 pints it goes off before you can use it. So I was only getting a four pint bottle.
I don't use formula and I don't buy fruit or veg at the supermarket either - local shop is cheaper/better. I have never seen a market stall that accepts tokens.
Where and how do you use yours??
