In most of the cases [tag]Clickbank[/tag] is the best option and there are number of reasons to this. First of all Clickbank has [tag]marketplace[/tag] which allows affiliates to find your electronic product and promote it. Secondly, Clickbank takes control of affiliate payments and sends you a cheque every fortnight. Finally and most importantly, they take care of credit card validation and payment transaction which accepts most common credit cards as well as [tag]Paypal[/tag].

The only problem with Clickbank is that at first they will only allow you to sell a product up to $97 until you make a few sales and establish yourself as a merchant.
