Just a heads up,don't know if subject has any prior posts.
Did you know that if you purchase anything before reaching the 12 mile limt you are charged a sales tax for the Tampa Port Auth.
It's shown as TPA tax. Purchased a bottle of wine at first sitting and noticed it. It was also on purchase of a bucket of beer just after boarding. Next thing maybe all the ports of call may want part of the nickel dime pie.
