Going OT briefly to clarify this comment...
She may be required to collect tax in many states because of inter-state agreements (it's actually called a use tax when selling outside of your home state), but it's the tax rate of the state in which the sale takes place and is to be remitted to that state, not your home state. The purpose of the agreement is so the state loses no revenue by allowing out-of-state retailers to operate within its borders and so the state's own retailers do not operate at a disadvantage.
In no case, when purchasing within your home state/county, do you owe sales tax at a different rate than that of your home state/county. Since New Hampshire's sales tax rate is 0%, the class instructor/seller was definitely out of line.
Now back to your regularly scheduled discussion...
