I joined Borders Rewards when it first started—hey, it’s free, right? The only problem with it is that they are a little too good at coming up with deals that lure me in. Saturday, I took advantage of a coupon good for 40 percent off one book.

Today, I checked my e-mail and found a coupon for 40 percent off movies (limit three). It’s only good today and tomorrow.

Guess what I’ll be doing after work?
