Too hot to do anything but sit today, so I decided to spend some time listing my half.com inventory on amazon.com. (Half.com is rolling into ebay, which charges a listing fee; amazon.com charges a higher commission, but only on sale, and their shipping reimbursements are higher.) I started listing 30 books two hours ago. By the time I'd finished, I'd sold two; since then I've sold two more. Not the ones that I'll barely make money on, either... I've cleared about $25!
