I imagine that everyone in the UK who is interested in the book trade knows that Tesco (a hugely powerful and successful supermarket chain) uses its clout to sell books at massively discounted prices. And they sell lots of them -- sometimes out-ordering and out-selling WH Smith by five to one. But what you may not know -- I certainly didn't until I went googling for something -- is that Tesco also have an extensive online bookstore.
I've been having a look at it, and my first impressions are that it's rather good. Limited, of course. Doesn't list every book ever published, and leans, as you would expect, towards the popular side of things. But you can find the paperback version of the GOB on it, if you want to.
What is more, you can use the site to buy lots of other things, such as DVDs, CDs, and the like. You can even download music.
Now -- I've spent a few minutes googling and can't find the answer to this -- did Tesco build all this from scratch? Or are they piggy-backing their online presence on the back of some other company which does the stocking and despatching? The latter, I expect. But who?
