Wasted about 45 minutes on the internet this morning trying to find Sierra here in Colorado. Here is what I came up with.
Sears reseller had it about the cheapest.
True Value also lists it at about the same price, but internet order only.

The usual suppliers around here, Wal-Mart, Target, O'Reilly Auto,
Ace hardware, Advance Auto, Car Quest, Tractor Supply, NAPA, etc., etc.
either do not list it in their anti freeze section or show it as out of stock.
The Peak official web site shows several stores that carry Sierra. I tried all of them within 100 miles of my zip code and not one has it in stock.
Maybe other areas in the country have it but we evidently do not in Colorado.
