I prefer books which have rating of at least 4.2 on Goodreads and 1000+ reviews. Higher the better.
Interval is sporadic. If I think it is urgent, then order it immediately, else keep in Amazon wish list and buy when there is a good discount or during sale. If physical copy of the book is expensive, then I consider kindle edition if kindle version is much cheaper.
