Online business that sells clothes, guy makes it in NY, any way to avoid the 6.5% tax?

We are small timers, but a 6.5% tax on revenue of our product is devastating. My understanding is that a Delaware LLC still needs to buy from his NY LLC, incurring some costs and taxes. I am not from NY, and am an owner, is there any way for our company to avoid this tax? (or links to how people do it?) – by hq overview canIbeMichael – –
