I've been selling cookbooks on ebay for awhile now, and there seems to be no rhyme or reason to how they sell. Some I've listed multiple times, and lost money by listing them, only to have it sell on another go round for an incredible amount. I usually try to schedule my listings on Sunday's, so they end on the same time the following week, as Sunday's are the day that has the most ebay traffic. Sometimes things are slower on ebay during the summer, because people have so many other things to do, but instead of taking a break like I usually do during the summer months, I plan on listing twice as much! My wife is really getting onto me about my cookbook collection because it takes up so much room, so she's making me get rid of most of them, plus a lot of other stuff I have.
