I thought it would be more convenient and cheaper than the portable drill battery thing plus all the manufacturing. I just thought I'd share a resource with the forum, but then again it could just be my OCD flaring up.
I know not everyone has the same resources, and/or tenacity for designing and manufacturing things, or sometimes a place to work out of, so I I like to give a little support with resourcing. It's actually part of my real job too.
A guy could go to a store and purchase a "Green Dot Money Card (any amount), and then open a "Pay Pal" account to make purchase's.
