"Granted I’ve never received a counterfeit."

The problem is you may not know. I have received several items from known brands that turned out to be low quality. I don't know if these brands just have started to make low quality items (very possible) or maybe the item was fake.

I just buy high value items in person. The local economy can use the money anyway. The rest I don’t really care if they’re counterfeit so long as they function.

Why on earth would you buy a Gucci purse from anywhere but Gucci? Caveat Emptor.

Some brands sell lower quality goods with the same branding/packaging.

Right now, there's an intersection of lower quality goods intended to be discounted with counterfeit goods flooding the market.
