A full description of what the problem is needs to be included with any returned product with your contact info, and proof of purchase. Even though you may have explained the problem to us, and been granted permission to return the product, we must have a written explanation and a contact number included with the product. It is also recommended that you include the name of the person from our company that you have been in contact with. You must send the item back to us in a trackable manner (USPS Priority Mail, UPS, etc.) and keep the tracking info of the returned product. Please give ample time for returns to be processed.

 PAYMENT AND SHIPPING DETAILS.

We offer great discounts on shipping. You only pay the full shipping fee on the highest shipping cost of your items, and HALF PRICE shipping on all additional items. Few offer discounts on shipping such as this. Our checkout system will automatically calculate your shipping discount at the time of final payment, providing you consolidate your payment.

You may receive a verification and tracking number shortly after purchase, but this does not necessarily mean that your product has shipped. It would be fair to say that 98% of products will be going out the day the shipping label is issued. On occasion, the product may not ship out until the next day after the label has been issued. Most products purchased late in the day will not be shipped until the next day.  

If you checkout and start over, the auto calculator will not recognize the multiple purchases, and there will be no shipping discount.

Help us ship your order promptly by including your physical address at checkout. If your order MUST be shipped to a PO BOX, please contact us. Additional charges may apply.
