How do they deal with sales tax? Connecticut has a 6.35% sales tax so if I buy something for $1, the total will be $1.0635.

They could do what every other country does, and include the sales tax in the shelf label price.

Paying cash, you would pay $1.05.

I'm referring to states that don't allow rounding.

It seems obvious to me they are already rounding to the $1/100. Why is rounding to $1/20 a problem?

Ah I see. Yeah I agree then.
