Thank you for posting this!
I was just about to order an $800 treadmill from a company called "affordabledepot.com" (their answering system answers as "my online depot"). It happened just as you said, craigslist posting, received an email from the company about 2 weeks later and they are requesting payment by loading up a moneypak then sending over the activation code.
Beware, they are using the name "affordabledepot.com" now.
