 Sales Tax

LowPowerLab is a limited liability company incorporated in Michigan, United States, and hence required to collect sales tax on Michigan bound orders.
Michigan Sales Tax: a sales tax of 6% is only applied to orders shipped to a Michigan address. For all other orders the customer is responsible to report/submit any sales/use tax on their own when required by their state or local government.

Payment methods

  • Major credit/debit cards securely processed by :
    Visa MasterCard American Express Discover JCB
    This site is HTTPS secured end-to-end and does not capture and store any credit card or financial information, it is only used to be encrypted and passed (also via HTTPS) to Stripe for processing.
    Stripe is a solid platform and we have had zero issues with fraud or anything else that should cause concern. Hence this is the default and recommended method of payment.
    When using direct card payments, you will be required to provide:
    • card's billing street address
    • card's billing zip/area code
    • card's CVC
    • Two out of three checks above are required for a transaction to be successful, otherwise the transaction is rejected by your card's issuing bank. Ensure each of these are identical to your card's billing address!
  •  (you will be redirected to Paypal site to make the payment, then returned back for confirmation).
    • Unfortunately due to Paypal's falsely advertised fees and exchange rates, a 1.5% processing fee is added for international transactions (applies to products and shipping). However along with shipping cost, this fee is non-duty (not taxable by customs). We strongly recommend the direct credit card payment method which has no such fee, however for those customers who insist they pay via Paypal, they have this option.
