Ok this one always kinda catches me out since in the UK we have our sales tax in the price advertised where as it's extra in the states.

So, what's the sales tax at the moment in "orlando" ? and knowing its different in different counties? is it the same at the florida mall as the millenia mall?

For small stuff it doesnt matter but if I get carried away, and I usually do, in the apple store, it can make a big difference
