Once you place your order, you can cancel within 3 days if your order has not shipped and your credit card has not been charged. Once your credit card has been charged, if you cancel your order, you will get a refund minus the CC fees (2.9% + .30). Unfortunately, the CC companies do not refund those fees so we cannot refund any of those fees back to you.
The same applies when paying with PayPal or Amazon Pay. For each of those, you will be refunded the full purchase price minus the fees (2.9% + .30). If you used your bank account to make this purchase, the refund usually takes 3 to 5 days for bank payments to complete and become available in your bank account. Additional time may be needed, depending on the buyer's bank.
If you received FREE BONUS ITEMS with your purchase, you will be refunded the order amount minus the bonus item cost.
