Yay for Teddy and Rigatoni recovering well! And matching zipper bellies! Do they have to wear funnels? I wonder if they'll try to lick each other's stitches.
In re: the Amazon marketplace thing. I made a couple of hundred bucks during my book clearing frenzy in the spring. I discovered that I needed to be careful with heavy books selling for less than 4 or so dollars. The shipping made it worthwhile for the lighter books but I lost a bit on the hardback cheapies. On the other hand, I sold a 12 year old textbook written by one of my professors for $40. And some other completely random things for much more than I expected to.
The more common, best seller types weren't so successful since the monstro-sellers undercut the price.
