Amazon and eBay seem to have every product going, even products that merchants are supposed to sell exclusively via their own site, so how do affiliates thrive in a climate dominated by these mega marketplaces? The only positive I can see with this is is that Amazon is such a highly trusted name that using their affiliate program will compensate to some degree. Work with the tide as opposed to against it. But it instantly reduces income from 30-50% offered by many affiliate networks and merchants to under 10%, the paltry figure on offer from Amazon. Also, Amazon's 24 hour cookie is so short that some potential buyers will no doubt buy after the cookie has already expired, so denying the the affiliate some sales. However, Amazon has excellent cross-selling of related items and because of their large inventory and trust, sellers could end up buying goods worth a lot more than intended. Is it best for affiliates to just promote Amazon unless the product cannot be sourced from Amazon and eBay?
