Affiliate Marketing Secrets

Do you know when you look up your item you are going to sell on amazon.com and it’s not there?? I know people make money off making the first listing of the item when people use it…For example: when you search “iPod Touch 4th generation 8gb” , there is a listing, that you can sell from. The person/company/amazon account who made it was “Apple”. And every sale that happens from Apple’s Listing (every time someone sells an iPod Touch from the listing “Apple” made), doesn’t Apple make money off it??? So my question is How do you make a listing on amazon.com, so people will be able to sell from your listing, so every time they sell something a percent would go to me????? Like My question is if you don’t find iPod Touch 4th Generation anywhere in Amazon.com, how do you make a post? It is hard to explain, what I’m trying to say…
