Good point, I've missed quite a few. I guess I was thinking more of "one stop shopping", which even PCC barely qualifies for only a select group of people. But at the end of the day, should the merger go through and Krogerson's tries to go all monopoly, the listed alternatives will serve as mitigating factor.
As far as "one stop shops" go, there are few in the PNW. I'm down in Federal Way, and though we have Fred Meyer and the Walmart Super Center, everything else (Safeway, QFC, Trader Joe's, WinCo, Grocery Outlet, Chefs'tore and possible Amazon Fresh, though I've not been in there yet) are just grocery stores, and Target and Costco (plus what we call "the old WalMart, used primarily as a management training store for WalMart) are big-box stores that also happen to carry food.
With the rise of e-commerce, I don’t really see the allure of one stop shopping.
I live in the PNW and almost never go to Kroger/Safeway stores. I just want groceries, I don’t want to have to wade through endless cruft to get there.
