Hello, I used to promote email/zip submit offers using Adwords. but Google raised the bids up to $1.00 and it's not profitable anymore. I'm thinking about alternatives to Adwords like YPN or Adcenter. Do they provide profitable traffics for email/zip offers? I need at least 300~500 visitors a day for ipod and giftcard related offers. Did anybody have the same problem? Any advice? Thanks.
