I’ve a bit of a reputation for making impulse buys. Not your typical kind of impulse buys either. By that I mean I don’t walk into Lidl for a loaf of bread and a pint of milk and emerge with a pair of skis, a plasma cutter, 15kg of de-icer salt and a rowing boat.

Well. Not all the time. I’ve self-imposed a restraining order on my visiting the middle aisle.

I tend to go for the more obscure stuff. Odd one-offs that appear in bungled Web and auction searches. Rarities that appear on super dodgy looking but actually legit shopping websites that you know will never be that price again if the site admin cops on to it (and the chances are low as it looks like the webmaster has yet to upgrade from FrontPage).
