Listing your own products for sale on other ecommerce website which accepts kind of products you offer seems to be goos strategy for improving the sale, but how do you make payment? Do they charge you for no. of products you list on their website or they charged commission for each sale? or there is fix kind of charges whether they sell or not?

Does anyone have experience with kind of marketing ?

It depends on the website and the kind of product. Some have free to list, but try to sell added ppc (e.g. download.com), other take affiliate commission and other again are just happy about getting more "free content". If you are into distributing software, take a look at XML PAD files which is *the* standard to use.

Remember: the key with affiliate marketing is get your affiliate link in front of an interested audience - how you choose to do that is completely up to you! With that in mind,
