I am about to start selling on Amazon and about to buy a UPC code. There seems to be two options. From the official GSI site which is in the hundreds a year and they only sell a batch of 1000 (i only need one).
But the other option is to buy an individual UPC/barcode from a reseller. But i think Amazon might be clamping down on these (not sure). What would you advise? I only have one product.
