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 dont 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. Thats what I go to Costco for.
That is an easily solvable problem. Just become the regular family grocery shopper and you'll learn the store layout in no time.
