SALES TAXES: 
Texas customers are charged 6.75% state sales tax. If the sale was taxable, so is the freight. 
We issue code numbers to Texas customers who file tax exempt forms with us. When a code number is entered in the space provided during checkout, sales tax will be removed from the e-invoice. 
Out-of-Texas customers are not taxed on our site. They are responsible for paying any taxes due in their own state.
