I had a problem with a few auctions on eBay right at the start, let alone real ones, so you have to be pretty rigid and say 'this is my limit and no more' - there is no point thinking, 'well it only went a few quid higher than I bid so I should have bid more', as you never know if you had bid more, it might have gone up more, and it is always just a little bit higher, and before you know it, you have bought a kay for £200! (caveat, I have not ever done that!)
