1.) Do you have any good template of a contract with your supplier about exclusivity of producing your product just for you?
2.) I want to add/change some accesories going with my product to uprgrade it. However I want to keep the ranking and do not want to start a new ASIN. Has anybody handle with that? My question is how you organize your stock. Because you have a wrong description (either old or new) for a certain time. Or do you sell your stock out completely before you get a new stuff on stock and change description? I guess I would loose rankings in this case. Any advice?
