Greetings,
Actually, we have already developed a website for a custom, which is similar to what you want but it is still in the final stage. Our client also want to develop a website similar to shopstyle.com. There are possible different ways to maintain it, see below but it depends upon how you would like to implement it.
a) You can do it thru' different networks like link-share/commission junction/affiliate window etc. In this way you can get the products from different advertisers, which would have been registered with these networks. Your site commission etc. will all be coming through these networks.
b) Built own APIs like that of shopstyle. Shopstyle has its own APIs for the products,categories etc. Through these APIs they have purchased the rights to get products from different advertisers, which might be number of dozens.
c) Through popshop API. We will suggest this way of implementation as it is cheap and comprehensive
My current bid is just a placeholder to submit the proposal, so please initiate the chat thru' private message board.
Look forward to hearing from you.
Regards,
YK
