"Congrats! You earned a Winter Gas Savings bonus credit of 20%. The credit appeared on your March 5, 2013 bill." ~Suck it heater!!!
This is a direct result of my opening the windows every morning and closing them every night to collect and keep heat during the winter. We only used the heater for the weeks before and after solstice.
My DW fully mocked me for doing this...It's all fun and games until some bitch gets 20% off!!!
