Interesting. This could be useful.
The developer portion of the site seems kind devoid of hard info: http://tapzilla.com/advertise
The article says it costs the developer $1 per download. Who is actually paying the money that is credited back to the customer? Does the developer need to fund this (in addition to the $1 per download), or does TapZilla?
If TapZilla is funding the customer credit with the developer's $1 per download, can this be used for apps that are more than 99 cents? And how is TapZilla making any money?
If the developer is funding the customer credit, then the developer would need to pay TapZilla $1 + cost for each download? If so, is this prepaid or postpaid?
