No, I haven't gotten DR yet, was pondering on it. But I haven't changed my Amazon login yet to get W off of it, probably would be best if she didn't see the purchase.
Just chiming in, but if you setup a new Amazon account, they will offer a 1-month free trial of Prime and you can still get the 2-day delivery on the book. I just got mine and about halfway through it, and while not ALL topics are relative, it's been highly informative and I'd definitely recommend it.
