Credit Card Refund Policy

IMPORTANT NEW REFUND POLICY: Due to a recent change imposed upon us by the credit card companies we will not be able to refund the credit card fees charged to us on any purchase made. The credit card companies have changed their policy and will be retaining the credit card fees from us and our customers regardless of the reason for a refund being issued This fee withholding policy begins 10/16/19. For example, if you purchase a $5,000 product from us we receive $4,840 after the credit card company takes their fee (this is a USA purchase example, international fees are higher). If the order is cancelled we can only refund you the $4,840 we received. This policy only applies to credit card purchases – check, wire transfer and cash payments will receive full refunds.
