Taxes vary from state to state. Here in florida it's 6.5%. the total cost would be about $64. Im not sure what state tax is in Colorado. But it's pretty easy to figure out total price if you know the figure.
I just looked it up and... I think it's about 7.62%

so it would be about $65-66 at the most
