I had the same problem finding it -eventually found a shop in Bismarck that carried it, Eco Chic I believe it was called. I really like the Annie Sloan but am actually on the look out right now for other brands that are easier to get my hands on. There is a Canadian brand called Fat Paint that you can find in Wpg, and another Canadian brand called Country Chic that I’ve come across out west but not sure if/where it sells around here? Mudpaint is a US company and not chalk paint but similar idea/results - you can supposedly buy it in Minot but the retailer is NEVER open. I’ve seen recipes for making your own chalk paint by adding plaster of paris to regular latex paint but haven’t attempted it myself. One of the paint stores in town (I think on Park?) has a chalk paint base that they will make any color for you... but I couldn’t find any reviews online for the brand at the time. Let me know what you end up going with, I’d be interested in any reviews

I’ll have to look into the above poster’s alternative too.
