All my recommendations are sane
- if you don't count that they recommend books I already have
. Mainly Pratchett books, interspersed with some historic novels that appear because I ordered stuff for my girlfriend and some sciency stuff, because I ordered some pharmacy books, too.
Then there are the odd music recommendations which usually are totally off because I don't buy music at amazon for myself, but quite often bought for my gf.
No worming pills for me, though.
