Think of it this way. They're getting a weak ass CTR and still pulling $800/month. That's an awful lot of Adsense clicks. What are those advertisers paying for his clicks? I mean, if you're running Adsense on a site, it's more than likely because you can't convert your own traffic. If advertisers are consistently buying that traffic, and they are making money off it, this could be a valuable buy. I guarantee the advertisers are spending far more than that $800 to make it. Someone who knows that niche probably just scored themselves a nice money maker with a bit of work, just by cutting the middle man out and snaking a good source of traffic. They have $31k to drop on a site, they obviously have some idea what they are doing...

Whatever the case, I would bet the farm that it wasn't an affiliate who made the purchase, but an advertiser with promotion of a specific product in mind.
