Actually, taking a close look on the site, I get the impression that they don't ship any disks to you. They give you download links. I am also getting the impression this is common cracked warez they are selling.

That's what they are doing - selling cracked software, a single key to multiple customers or key created with a keygen. This place is selling through at least 2 storefronts. A while back someone at my work bought Nero from one of these sites (truly not knowing that it wasn't legit). Not too long after, the key no longer worked with Nero updates because it had been blacklisted.
the way these sites operate is that they send you for example photoshop cs3 cd/dvd but without the serial numbers or registration codes, as they are sold as backup copies. So in essence you are paying $60+ for a backup copy of software you supposedly already own. and that is the only way these copies are legal.

There was an outfit called iBackups.net (unrelated to iBackup.com) that claimed it's business was replacing lost media for people who had legitimately purchased the software previously. However, they did provide customers with a (often non-functional) serial or key because the business was actually selling illegal copies. The 'replacement' bit was just their way of trying to game the legal system. Last I heard the guy who ran iBackups.net got a severe prison sentence.
The outfit discussed by the OP is probably in some jurisdiction that simply doesn't care about software rights - they've been around for a while. I find it humorous that they offer a money back guarantee - I wonder if they ever actually follow through on it.
