Can someone walk my dumb a$$ through this? So, I go into Walmart and I do what now?

I just want to be clear on the process as I'm sure the Walmart employee will not be.
Dumb a$$ #2 has same question(s).
BTW, this looks great, Yankee!

Please don't start in Walmart. Start at bitinstant.com and all will be clear. Once you get to Walmart with payment slip and cash in hand, you'll be handing both to a clerk there.
