I was prompted to google the above and was really surprised to see one of these locally in a very affluent town near where I live in Yorkshire.
I was impressed by their website and decided I could help in a small way.
Every time I go to the supermarket, I buy something, just one or two things at a time and put them in a box. A tin of mince, a couple of tins of beans, pease, vegetables, cooking oil, gravy browning, Every six weeks or so I take it to the Charity HQ. A pound or two on top of my shopping is not missed and it helps them a lot.
Have a google and see if you can help.
