Which magazine is currently investigating online travel sites such as Bookingsdotcom and Expedia, and the others, that tell you there are "only 5 rooms left" or that "last room booked 2 hours ago." They want them to be much more open, and to disclose where and how this information is gathered. There is a suggestion that it is a marketing ploy, and since they won't disclose how they compile such information it is impossible to prove or disprove that suggestion. Far from me to suggest that Amazon would be guilty of that kind of behaviour to sell books. Could it not be people putting books into "shopping lists" and then talking them out again, or just deleting the entire list? It does seem to be a lot, considering none were sold, but it is starting to run up to Christmas and people might be creating "wishlists". Less likely, but could the books be given away? As an Amazon staff benefit of some kind? Otherwise, they just have very bad stock keeping, and five of your books were stolen?
