So I'm attempting to institute a daily policy of "One Less Thing". One thing goes in the garbage, the goodwill bag, onto eBay, or onto Bookmooch. Which, by the way, anyone with too many books should check out:
It's a book swap website. Get a point for giving a book away, use it to mooch a book off someone. The cost of media mail shipping is low, and you're basically getting a book for the cost of shipping another one to someone else. You can specify mailing within the US only if you don't want to deal with international shipping, which I certainly don't. Dig it.
