Maybe you are and maybe you aren't. The law says you have to pay sales tax on retail purchases, and that the shop has to collect it and remit it to the state department of revenue.
If you find a shop that will help you break that particular law in order to get a sale, good for you. Up to you and your personal values as to whether you take them up on it. (It's not like we all drive exactly the speed limit, you have to decide what works for you.)
I run businesses and sales tax and payroll taxes both scare the hell out of me - I make sure I am clean on both, just helps me sleep at night.
