The availability of Collinite products over-the-counter is kinda hit-and-miss.
Some of you bought both the 845 and 476S at Harbor Freight, which no longer carries it. Some get is at NAPA auto, but not all stores stock it on the shelf.
I get mine at a marine supply store, but the 476S is sold as 885 and the 845 is sold as 925. They are identical, as when you look at the Material Safety Data Sheet (MSDS) on the Collinite website, they refer to both waxes. It's just another option for you if you want to spend the money locally at a brick-and-morter business.
I use the 885 on my daily driver (Subaru Outback) here in the Frozen Tundra of Lambeau Field (Literally, 15" of snow yesterday and -2°F temp outside today) because it last most of the winter and it looks great. As an available over-the-counter (OTC) wax, I recommend it over the other favorite OTC, Meguiars NXT 2.0 for that reason. Where this wax REALLY helps is when its on the door jams because the door seals don't stick to it when the snow melts from the heat of the car, and then freezes when it sits outside or in an unheated garage. (Yes, I treat my seals with AeroSpace 303 protectant as well.) I've seen people pour hot water on their doors to open them, drive off, and I KNOW that they will just have the same problem at the next place they stop (like at their work parking lot).
Just a common-sense detailing process to prevent a winter-driving problem.
