ARE DRUG CHAINS EATING GROCERY RETAIL SALES; (Not to mention my neighbor's bulldog!)

Over the past 3 years, I'm not sure my family & I can remember a time when we bought our break, milk, eggs, cereal, etc---at the mega grocery "takes me 30 minutes to get a quart of milk"---stores. And lets not even get into snack food sales, once the kids get out of school, or the ready-to-eat lunch items, from the local tradesman. Over the last 3 years the so-called "Big 3 Drug Chains" seem to have all aggressively moved into the "100 yards-away-from-my-place-ever-so-convenient" grocery business. Let me see. That's about 20,000 stores now encroaching on the neighborhood grocery business over the past few years, and I've yet to see the "super-smarter-than you & I analysts" even mention this? Funny how they blame grocery chain store stagnant sales on everything, but the totally obvious. Some quick back of the napkin doodling, poses the following: Let me see. Population in USA fairly stagnant. Grocery sales thus pretty slow growth. Makes sense. And now, the 20,000 or so drug-chain stores have begun to focus upon everyday staple grocery items. Hmm....yet the cause for the stagnant sales in the chain store grocery category, according to the Spock-smart analysts, is the on-line-boogie man-monster, which still has no logical answer, for delivering fresh meat, fish & veggies (and ice cream, of course)---to the rapidly expanding city apartments? (Wait, sorry......I have to go now. Emergency at our place. The neighbor's bulldog, just gobbled up the steak which our on-line shipper dropped on our doorstep. Glad it didn't take the ice-cream!)
