In my experience the stock levels are really bad, they claim an item is in stock, and then when it gets to shipping it turns out not to be in the warehouse. They did this to me twice for the same order, and only informed me via e-mail 5 minutes before the phone lines close, so it wasn't possible to change the item to one which is in stock/on the shelf. The best way to solve this issue is to provide realtime stock levels which are accessible through the website, so the purchasers knows that if there is only one item in stock, then it is a risk they take. Oh yer - I also managed to get Scan to change the order to a Saturday delivery (for a slight surcharge), but that was one of the times they claimed an item wasn't in the warehouse. I phoned on Saturday to complain, but there wasn't anything they could do until Monday, and they couldn't say if items would then be out of stock when picked. It would also be useful to provide an option to part ship items if some turn out not to be in stock/warehouse. This should be done at the point the order is raised. I've now learnt to order the items via the phone, as then I can be sure of stock levels, and the items SHOULD be kept for the order, and possible to get them to check the stock levels in the warehouse.
