Find cheap books on https://www.bookdepository.com/
Book depository has one of the most complete book collection (at least the books I like) and they generally have good prices and generous discounts. However, instead of checking every time if one of the books I want is on discount, I decided to create a script to do it for me. This R script (using Rvest) scrapes data with a search_term provided and then shows me the book that have a discounts equal or better than I search.
For example, find_books(search_term = "Learn Python the Hard Way", perc_discount= .3) will return any version of Learn Python the Hard Way with a discount of 30% or more!
