Books

I have many books that I need to get rid of. My house is over flowing in books. I have been contemplating on what to do with these and thought I might offer them to my readers on here. However, shipping can get expensive, since I do have many to get rid of. I was wondering if any of my readers would be interested in getting a book and only paying me for postage? I was thinking of having a postage fee of $3 and that could be sent to me via paypal or regular mail and then I would send out the book you have requested from my list. Would anyone be interested in this? Or if you have other suggestions, please comment below.
