I've sent paid traffic to direct CPA offers before, it's a gamble,
because I'm assuming the traffic you bought isn't targeted so maybe
1-5 in every 5k will go through with the offer. Once I paid $25 for 20k
traffic, and made $40 off the CPA, and once I paid $50 and made only $11..
It's a risk, unless you have laser targeted traffic. Good luck.
