B.Y.O.M. is Bring Your Own Mug! What a difference it would make if everyone brought their own mug. Rick takes his mug to the gas station and fills up for FREE! Of course he had to buy the mug first but it saves us money over time. The mug paid for itself. Check out the stations in your area to see if they have this option.
If everyone used a mug at work instead of the paper cups we could save thousands of trees a year. This would also decrease what is dumped in landfills every year!
