Lesson learned: just because I had a hassle-free experience purchasing from an online merchant 6 months ago does not mean that I should trust them again for other purchases without checking ResellerRatings.com first.

Turns out a merchant that I bought from a while back has been getting tons of "Very Dissatisfied" reviews as of late, but I hadn't checked. Well, at least I was able to cancel the order, and my credit card company is always on my side.

Still don't have my goodies though. Poop.
