Some third party products are good, but the junk makes search difficult.
I find it very easy to separate the crap from the good stuff on line. So easy to go down the line of items on line. Easier than walking around a store where you don’t know where things are. On known items I tend to buy brand names. I like brand names. I like tropicana OJ and Kleenex tissues. Neither of which I buy from Amazon. That’s what I go to Costco for.
