Do grocery stores REALLY recycle plastic bags?

For many years I industriously gathered together all my plastic bag products and dropped them off at Cub Foods, and kept doing it for quite a while after China stopped taking our plastic refuse and grocery stores reportedly stopped actually recycling plastic film. There is no way to actually tell what is going on with plastic by looking at Official Online Sources, which clearly haven't updated the verbiage on their plastic film recycling page for decades and are still unintentionally promoting a lot of wish-cycling. So gradually I just started throwing plastic bags in the trash. But there is still a big bag of them on the front porch so I decided to do a more in depth search to see if it was worthwhile hauling them down to the grocery store.

The answer seems to be "Yes." Apparently grocery stores are recycling plastic bags again for real, not just wish-cycling. At least according to this website, which seems to be written by someone who knows what he is talking about. He does more than just assert that stores are recycling; he provides a link to Trex, the world's largest manufacturer of wood-alternative decking products, which lists all the stores they pick up from in each state!   And sure enough, there is Cub Foods listed for Minnesota. Okay, that is sufficiently specific to be believable. So that bag of bags is headed for Cub.
