What solution did they give?
You have to remember two things:
1) If you go for an add that already has a high EPC, then chances are it's been run for some time and well optimised. This means that your offer is likely to have already been seen by your target audience.
2) A lot of guys running offers with Adcombo are running whitehat offers, but promoting them with blackhat methods. I can almost guarantee that if you run the varikosette offer on it's own, just promoting the product and directly linking to it, then you will struggle to make a profitable campaign. You need to run the angle that it's a miracle cream and use a prelander that appears to be a 'genuine' blog/magazine post about this scientific breakthrough.
