eBay

Selling Books in Bundles is probably the way to go. As it saves buyers doing the collecting. However postage is the killer with books.

My dad owned a 2nd Hand Book Shop in a small town in New Zealand. It got rough for the 2nd hand book shops when Trademe, Ebay and Abe Books came along. Dad would occassionally sell on Abe Books and Trade me. But it ended up being alot of work for him...

No such thing as a free lunch.
