Any sale comes with 'No return' policy, unless merchandise is damaged in shipment, you should inform me right away in this case.
All reputable entities, books stores, libraries, specialty stores, universities, schools, can have a 90 days credit term on books in quantity of 50 units and up, but no return of books ! Please contact me for credits : email@example.com I don't want to offer phone number here because of telemarketing problem, but if you are serious, ask and I will give you the number to call so that we can talk. Remember, you can ask for free books on some of the titles, I fully support persons who are eager to have knowledge but lack of funding, especially those in third world countries. All books are brand new, some are hand crafted !
