Masserant's Flatrock

Hey all! Did you know that Masserants sells propane refilling? You don't say?! Have you ever CHECKED your propane refill before?! Think Masserants has good refill prices? Would you think they did after they jip you 22.5%?? Would it still be a good deal? They did not fill my propane tank to its limit, instead, they stopped 22.5% short.
