Unfortunately, this is not enough anymore. Amazon commingles their legit inventory with 3rd party inventory that drop ships from their warehouses. They don't differentiate between the two inventories, so you can still end up with a counterfeit product; even when "Sold and Shipped by Amazon".

I've actually had better luck with 3rd Party sellers that ship on their own (not from an Amazon Warehouse). If they send you a counterfeit, their store reputation is going to take a hit. Though at this point, eBay might be a better option.

Lately, I've started buying direct from the manufacturer when possible, or shipped from B&M store. Their prices are the same, or better.

The 3rd party market place on Amazon has become Aliexpress with higher markups. Unless I have an immediate need and I can not find the item locally, I just order it from Ali.

Yeah I wish they'd just let me perma-select prime. Not even risking getting burned.

I didn't know they used to have that filter though. That would be super useful to make a comeback
