You can buy just about anything new from anybody in any state and not pay the taxes directly to the out of state seller
But it is absolutely your responsibility and obligation to report to your state any and all out of your state purchases in a specific calendar year that you did not pay taxes on to the out of seller so your home state can send you a bill for the amount of taxes due on those purchases
If you don't you are in defiance of the law
How many ads have you seen that say if you are a resident in the same state as the on line seller is you have to add/pay that states sales taxes to the purchase
Are you a law violator for the sake of your hobby ?????
