Bandwidth for the videos was provided by Amazon S3 directly[1]. So if he brought in half a million dollars in 5 days from selling his video at $5, that's 100,000 purchases, and if everyone only downloaded the 720p video at 1.2GB that's 30TB per day, hosted only at Amazon's Northern California location, it would end up costing almost $10,000 in bandwidth (priced as an entire month). Shit aint cheap, but at $5 each, he makes a decent profit. That's just for the 4 days he provided numbers for.
[1] The link download link ends up resolving to http://download.aws.louisck.net/ (even if you stuck the video filename on the end of that, it's a signed URL, so you're SOL unless you go through his website after paying him money)
Oh yes, I am aware it was hosted directly by S3. So $12,000 for the website itself, then another $20,000 in infrastructure costs (S3 hosting, cloudfront or whatever else he used to host his actual assets, something to do dynamic pages and PayPal integration for instant receipt of downloads for buyers).
The $32,000 number quoted at that point is not even that bad.
