I don't think I have used cd wow in a good year or two now, well not since I used to buy the region 2&4 Sopranos for £22.50 a season. Back then the cheapest price for a region 2 season was around £55, £60 ish on region 1. The packaging was better compared to the region 1or2 boxsets as well (a nice slim plastic case), same features and sound though but for less than half the price.
I stopped using them as I got fed up with almost everything being out of stock, or waiting around two weeks for delivery of instock items. And this was before their warehouse went up in smoke. It's a shame as they were generally pretty good a few years ago, and the cheapest on price.
I normally use play as their stock levels are very good, excellent service and good delivery times. When I ordered all 20 remastered ultimate edition Bond dvd's for xmas in their bogof deal the other year I got an e-mail from play the next day,saying my account had been frozen and asking to ring them up urgently. As it was an unusually large order for my account they wanted to find out if I had actually made the order or if my account had been compromised before proccessing the order. Really impressed me, you can't beat customer service like that.
