There's a few that I'd like but all my paper ones are packed for the move. Since they offer an ebook+pbook bundle for only a few dollars more than the pbook alone, I suspect that may be a regular thing. I hope so.
As for the sale, they got me for $70 ... which is something like $250 worth of ebooks. Got a couple I'd been looking at in paper but couldn't justify dropping $35 on, and a few other goodies. Unfortunately, I still haven't been able to download all of them. "Due to heavy server volume you may experience trouble downloading your ebooks." I assume "heavy server volume" == "every geek in the known universe disposing of all their disposable income on the O'Reilly site right now."
This is my day for deals -- I was looking for a particular garden plant, and just happened to hit a short-term sale on a nursery's website, and ended up with over $100 of plants for under $30, too. I'm dangerous around a sale; I'm not really sure if I actually need an olive tree, but now I've got one. Or will, anyway, once it's delivered.
