Once you've bought something you must never, ever, look for a similar one elsewhere, it will always be better or cheaper. Even at the show the other week I spotted a couple of things at Frank's Caravans stand that looked to be a great deal, but I waited until I'd been round everyone else first before I parted with cash. Turned out he was best by a good bit, but you can't be too careful. One of them was a kettle funnily enough, I paid a tenner for it but now you've spoilt my day!
