Watching For the Mailman

Every semester I get a little more confident about ordering used books online. This time I took care of books for four of my six classes that way. In the process, I bought from five different sellers (all through Amazon.com's used book marketplace). I haven't been burned yet, but I've never cut the timing this close, either. I'm expected to read material from a couple of these books before Tuesday, six days from now. Here's hoping expedited shipping comes through! I figure it's worth the risk: even after shipping costs, I'm saving more than $200 vs. the campus book store.
