I live in Dubai and public libraries are almost non existing and with bad English supply. I will be going to Miami this summer, and I am thinking of buying some FI books, i.e "Meet the frugalwoods", JL Collins book, "your money or you life", etc, but I don't want to pay full price. Besides Amazon, is there any online site where you can buy second hand books from?. I don't really want PDFs or Audiobooks, I prefer the old fashion way of reading a book. Thanks
