I have been so excited about used books the last few months of being back in the States!
There are so many ways to receive used books. Used book stores, thrift stores, online, etc!
I have gotten the most books at Goodwill lately, but the only thing with that is that it is random and you have no way of knowing what they will have.
Used book stores are the bomb, but sometimes they are a little pricey. My favorite used book stores that I have been to are the ones that you can trade books for credit and that have books that are lower than just half the cover price.
Of course you can find almost any book on eBay, but sometimes it's hard to find them at a good price. I have found great books, but a lot of them charge a silly amount for shipping. As long as you are willing to shop for the best value, you can find what you are looking for.
I just came across this new website for thrift books. They have tons of books and they offer free shipping over $10 and they consistently have coupons!
Amazon offers used books, but most of the time used books require $4 just for shipping, so I haven't gotten a whole bunch of used books from them. Of course, they have just about every new book ever if you want to buy new!
I enjoy used books so much! It is so cool to read a book that has a history and that is being recycled. It's also way too much fun to search for used books and find what you are looking for! I have found several childrens' books that I used to have when I was little and it has excited me so much to have those to read to my little dude and eventually to his little sister!
