This doesn't work unless you have someone verifying that products from both sellers are identical. Seller A could be selling real logitech gear and seller B could be selling clones, as is common on poorly policed markets like Amazon and Aliexpress.

And most of the products I've seen "grouped" in this way haven't had identifiable branding, they were just generic functional products like "heat shrink", or "M4x20 screws".
