book selling...sigh

So, I'm pretty broke, which means that I'm looking for interesting ways to make money. Short of prostitution, there's not a whole lot that fits my schedule (seeing as I'm in class during the day and have nights free...wink, wink), so I've taken to selling books on Amazon. I'm hoping it works out. I have twenty-one listings right now and if I sell all of them we're talking a good $300, which is probably zero profit, but hey, I need the money NOW. In addition to selling books on Amazon, I plan to try to sell various crocheted/knitted items on Etsy (and bound books by yours truly!), but it costs money to list the items, so we'll see how it goes. If anyone has any other ideas (other than moving in with my parents, dropping out of school, or selling sex or drugs), please let me know!
