I used to buy returnables in the Michigan UP until Pepsi gave up and shut down their line. I remember my disappointment when I went up there several years ago now and found that the returnable section in the grocery stores had shrunk by over half. (The first time I was up there, was just after the "Big Slam" 1 liters had come out, and I found that Pepsi there still had the "original" big slam, returnable quart bottles. I think they had just discontinued them, but I bought all the ones I could find.)
As for Coke, I remember that they bottled Cherry Coke up there at one point, the only time I ever have seen that flavor in returnables. But this was all in 16 ounces. I never did see these 10 ounce bottles for sale there. I wonder how they are distributed/sold - retail 6-packs or full cases at groceries and C-stores, or in captive vending machines only like Pepsi does in Memphis, Missouri, or if you can only get 'em the straight from the bottler.
