Hi metro99,
Sorry I'm a bit confused with your post, you mentioned you're in a position where your purchases are exempt from taxes but towards the end of your post you said you're worried about appearing more expensive.
The later seems to contradict the former unless I'm missing something in between.
Would love to help in anyway I can but I need to comprehend a bit more of what you're trying to say, kindly clarify :)
Cheers!
