I've added the latest and greatest product.
Right now we can only have one design per item until I upgrade to Premium shop. So far we've had a couple license plate purchases (thank you!) but if you all would let me know if this is a great t-shirt idea I'd appreciate it. If so, I can make these in increments of 5 MPG for a whole range of mileages. It will cost $60 from my budget, so I need some reassurance that it will be worth it!
