I told Mohammed Khan (Best One, Washington, Tyne & Wear), I'd ask the audience. He needs about £100 a week in change (1p, 2p, 5p, 10p and so on) and he used to get it from the Alliance & Leicester at his local post office. He's had a falling out with the post office, though, and is looking for an alternative.

I put him onto CoinStar to see if they had anything suitable, but they do not. Mohammed is convinced that he read something in the magazine about five years ago that held the answer. I honestly don't remember writing (or reading) about this. Most of the calls I get about cash are from retailers complaining about how much the banks charge to take their money.

Over to you, dear reader.
