Losing commission to Voucher Code sites

How is that? Just sounds like a bad referral system since modern customers will search around before committing anyway. Have you considered making sure you have vouchers on your site for retainership?

WoW, I would take it easy, these "parasites" offer more value at the end of the day for the end user than a content site (you don't believe ? well, if they didn't they wouldn't left your site to visit theirs)

People know what they getting out of these parasites ( Saving Money ),they can trust that those "parasites" are not giving them questionable feedback to make money

I understand your frustration, but you need to understand the market is changing, online shoppers are more savvy shoppers and smarter today more than ever, if there is something that your visitor need and you can't offer them, maybe it is time to think how can you figure it out without loosing the customer, or maybe you want to consider how to make money with these sites.

With this being said, i can assure you those coupon sites, may feel the same about reward and cashback sites that provide a better value to end user, the users understand affiliations and how it works, and they would by pass a coupon site by clearing their cookies to get some of that money back if needed.

If people are researching products, they're likely searching for reviews and bonuses. So...keep them on your site, retain your commissions, and seal the deal with high quality reviews and bonus packages.
