I don't actively use Amazon's program, but being in Colorado I see this as a big problem.
Instead of changing to comply with the new law, Amazon is shutting the program down.
I don't blame Amazon for shutting it down, but I'm wondering what this means for the future for online sales in Colorado and across the US.
