Only last week?
Try last year...
Bob's service is very erratic, and often for no apparent reason. As has been said, there really shouldn't be big deal with e-books.
Some things have been sent to me by return, while I am still waiting for others, which were pre-ordered, or which required physical items to be sent.
Bob does sometimes give bonus downloads as compensation for delays, so he's not all bad. Overall, though, the service is really not up to scratch.
A few weeks back, he was offering to sell something I had wanted for some time, and which is quite rare. I was poised to order it, then stopped myself; I fully expected not to see the blessed thing any time this year. It just wasn't worth the risk.
