Hi.. I was checking out bigdropship's FAQ page & this is #17
"17. Do you allow your products to be sold online? If not what are the restrictions?
Our products cannot be sold on eBay or any other auctions sites. We prefer that you sell our products on your own website. You must have your own domain name. Amazon is accepted"
I don't know how aggressively they would pursue any breach of this term.
So its either sell our stuff on your own site & keep it off auction sites.
