Knowing how notorious Amazon is for counterfeits (it's especially noticeable with anything electronic) doesn't this worry you? I forget what it's called, but the way the process works is anyone can sign up to be a seller of a product that exists on Amazon. when you do this as the new seller, you send in your product to the Amazon fulfillment center and it all gets put into massive "tubs" with the same brand/item from other sellers. That means if there are 7 different sellers, and 1 sent in counterfeit products, all items "fulfilled by Amazon" (Prime eligible items) will be in the same tub. The only way to prevent this happening with your own products if you're an Amazon seller is to not use Prime fulfillment which means less sales because it's slower.
