Not everyone in this game is a developer nor do they want to spend time & money on "custom-built solutions" when they can purchase a simple, easy to use .php script that does it ALL for them.
Last I checked, this is performance advertising where time is money. Not to spend time on "idea's/codes" in order to get something that is already inexpensive, for free. It's $297 which is less than $1 per day over a year that will make you a minimum of $50 per day. There is no argument here.
I'm not sure where you saw a $400 price tag but it wasn't cpv:Lab
