I'm not sure if you understand what commingled inventory means.
When inventory is commingled, Amazon puts all of the sellers' products (for a given product ID aka ASIN) into one urn. When a user makes a purchase of that item from any of those sellers, Amazon retrieves an item from the urn and ships it to the purchaser.
As a purchaser of items sold by multiple sellers with fulfillment by Amazon, it's not possible to know if each seller has their own urn, or if it's a single urn for multiple sellers. The distribution of the urn by source is also unknown.
I won't purchase easily counterfeited objects from Amazon, unless there is only one seller listed, and if that seller is either Amazon or an account that seems like the manufacturer. A random Samsung sd card[1], though; who knows . Something like this Anker usb car charger [2] looks reasonable (I'm not specifically endorsing Anker, usb chargers are just a product in a crowded, junky space, and Anker is a brand that's trying to present itself as selling good products.
