Odd I try to sell products that make way more than $10.00 per sale. Why would you want to sell low price products that earn even lower commissions?? It is not easier to sell cheap products than it is to sell more expensive products.
What is an IFW?? While it may seem easier there is data that shows people will buy items with higher price easier as they trust the product more due to the price. Sort of subliminal thoughts of course but look at a Toyota Avalon and a Lexus If you buy the Avalon with all the bells & whistles you basically have a Lexus at $15,000.00 cheaper...... So people buy the Lexus for more money, simply because of the badge and price point...
It's an incentivized freebie site. People go there to complete offers to get credit to be other people's referral. They get paid for being a referral, and trust me, they look for the cheapest things they can find. They go there looking to make money, not spend a lot of it.
There is many products that you can sell on your site. Try azoogle.com and there ringtones offers (10$+) or diet/semi-adult/adult products that you can find in my signature - 3th link.
Generally an IFW makes money because the affiliate network pays the IFW each time a new lead is generated - usually in the form of a new customer signing on for a trial; cost to the customer at that time being anywhere from $0 to $5 on average. Then, after the customer completes enough offers to meet the requirements of the IFW, they are considered "green". At this point, the person who referred them (their sponsor member) will pay the referral for going green, because the sponsor member gets paid an even higher amount by the IFW, because the IFW made even more money from the affiliate network when those leads were generated. I don't see how selling low cost items straight off of your site will fit into this system of moving money around, but I guess I could be missing something.
