You know, that site has pretty lax security 'standards', since, if you follow the info they tell you about how to enter the coupon and such, they then transmit that exact info to your e-mail address... They should have masked out the coupon number, or do the last 4 digits like most other places do.
Which would mean, there is a chance that, that info can be captured... not that it matters much in this case, but still... Yeah, the site is listed as a authorized coupon partner, so I am just nitpicking.

Still a nice deal for people who can't find any decent converter boxes, and want to spend as little as possible.
