I've bought quite a few books from TBD (I especially liked their 10%-off vouchers on prices that were already rock-bottom
). But I'm afraid I think things
will change. It was clear that they were heavily focussed on competing against Amazon, usually selling their books for 1p less than the Amazon price. Still, it was making a reasonable profit (£2.3m on sales of £69m a year ago, reportedly). Now there's no longer any incentive to push so hard to grab market-share away from Amazon, so something's going to alter.
I can't see the print sales division lasting much more than a year after the buyout. Remember
Bookpages? No? It was bought by Amazon as well... I think the international supply-chain and the operations hub in Egypt are the main attraction to Amazon, and those operations will get folded into the parent company. This
might mean that Amazon starts becoming less expensive for those outside the US and EU, one can only hope. But from a UK perspective it's certainly not good news - active competition is the only thing stopping prices from drifting up.
