Well that's interesting but I've never tracked Amazon.
However, we are off on holiday soon to Florida, and we booked a hotel at say £800 for a week on one of the price comparison sites, and I had barely pressed "pay" when husband who was on his computer, said "Guess what, I've just found the same resort for £610 from a different site" (not on the price comparison list!). So irritating!
Luckily the site I had booked with we could cancel at no charge. So we did, booked the cheaper price, only to have the bank phone husband to check what was going on because all this happened in the space of half an hour. It is ridiculous though, and enough to drive a person round the bend.
Recommendations please, for a stopover on the way to Loch Tay
