We have alot of control over the ordering process... as long as things stay the same size square we pretty much just pay for the vinyl cutting since we're doing the actual graphic design and vector formatting ourselves.
So yeah one can say MSP, one can say MP5, one can say TOM, or maybe SRT... heh just kidding. Any three letter word is pretty damn easy to get since all I have to do is type it in and send a revision for that order.
Its the same price for 19 vinyls if we do 19 different graphics the same size. When we hit 20 its about $2 cheaper for each cut by their pricing.
