I know that Sat Navs are one of the must have gadgets at the moment but I have been staggered by the amount that some (especially the new or nearly new ones) have gone for in comparison with other websites. Currently (12/11/07) Amazon are selling the Tom Tom One XL UK for £155 with free super saver postage and Comet are  £150 with £6 post and packing also available.

Why is it then that I have seen virtually all of the ones I have watched or bid on go over Amazons price? Remember don't think that, as its on eBay, its always a bargain. Do lots of research first into pricing and then ensure that you do not get carried away when it comes to bidding.
