My experience with EPN

I'm in EPN from 2 weeks and I'm earning well but EPC is too low, we're speaking about 0,16 ? on my total clicks. I'm promoting eBay's products by mail (i've asked for autorizzation to do this). Now I've provided about 600 clicks to my affiliate links. Actually I'm promoting used iPhones and 90% auctions (because is simple to place offer and not buy directly).

I'm here to any suggestion to get more sales and get high with my EPC.

what is a epn? do you mean vpn?
