I don’t doubt 1/3 of Walgreens could close. And Rite Aid and CVS, too. There’s the ghetto problem, and then these chains just built too many stores too close to each others. And those great looking new Publix supermarkets with pharmacies are popping up in most all the same towns as those other three in many areas.
No publix where I live. We have Kroger. I still think there is a place for local drug stores, but like you said, Walgreens is overbuilt for current times and thanks to democrats pro-thug policies...many are going to close in those areas.
San Francisco has lost most of theirs as stealing isn’t prosecuted.
