PLEASE BE INFORMED THAT AT "CHECK OUT", WHEN YOU PLACE AN ORDER AS A REGISTERED ACCOUNT (NOT AS A GUEST), WE WILL BE ABLE TO APPLY CREDIT TO YOUR ACCOUNT, IN CASE THERE IS ONE, IMMEDIATELY UPON COMPLETION OF THE ORDER. OFTEN, THE UPS SHIPPING ESTIMATE IS MORE THAN THE ACTUAL COST AS THE EXACT COST IS ONLY KNOWN WHEN THE ORDER IS PACKED, MEASURED, AND WEIGHTED. IN THAT CASE,. WE REFUND/CREDIT THE DIFFERENCE BACK TO THE CUSTOMER, AS WE DO NOT MAKE MONEY ON THE SHIPPING. BE AWARE THAT WE DO NOT CONTROL THE CARRIERS' RATES AND CAN NOT INCLUDE THE SHIPPING WITH THE PRODUCTS AS OUR PRODUCTS ARE OF VERY LOW COST.
