uhh, one of those picks are like $200 the last time i checked.. Also remember the dumb 4,2,3,1 hack with the buttons? You can see how much money it holds, what bottles are left ect.. you can also make it say "ERRoR" and go tell the clerck it ate your money saying that for a free coke
just press the buttons (from top to bottom , 1 -> * ) 4,2,3,1 and press the first four buttons to find the "ERRoR" message.
