We do—due to state laws, we charge sales tax on all purchases in states where sales taxes are applicable.
The sales tax is automatically calculated based on your shipping address and may vary by zip code within a given state.
You will be able to see the sales tax amount before you check out, and it will be included on your order confirmation email.
You can use this sales tax calculator to check and see how much sales tax you may pay. Please note that it's an estimate.
