Not long ago I sent in 2 old cell phones to a company. I went to the website and gave them the type and condition of the phones. They then quoted me a price ($80 each), sent me a box, and then sent me a check for the amount within 2 weeks of receipt. This got me to thinking.
Logos should have a trade-in program for paper books. They could do similar to the senario above, and then give you Logos credit. They could then find places to sell the books like amazon, ebay, or even college campuses through the campus or campus bookstore websites like ecampus or textbooks.com. They could also donate the books and take a tax right-off.
For example, I would like to buy the Raymond Brown collection:
Raymond E. Brown Collection (5 vols.)
I own all of these books in paper, and I cannot justify the purchase until my present copies are sold. It may take me quite a while to sell them, and I will probably not sell them all at once, which means I will be left without some of these volumes for a long time. I don't expect to get the full amount to purchase the Logos set, but I should be able to get at least half of the amount. A trade-in system is exactly what I need!
It is hard to sell books if you only sell one here or there, but when you are selling in bulk like Logos would be able to do, then I think that they could actually make a profit.
