I see there is only 15# in the tank. It says right on it (Blue Whino).
I hate to drive all around and spend $10 in gas just to save $2 in propane. There is a refilling place about 5 miles south of me but a kid got killed about 5 years ago refilling propane tanks there.
Wally World have exchanges? I just called them and they said $17.97 for exchange to they are in the lead so far.
