Priority Processing

Select the Priority Processingoption in the shopping cart for $1.98 and guarantees your order will ship from our warehouse today.

Adding Priority Processing to your order lets our staff know that the order requires immediate attention and needs to ship out of our facility today. While we guarantee that the order will leave our facility today, standard shipping rates still apply. If you prefer express shipping, please be sure to select either Next Day Air shipping or Second Day Air shipping when checking out.

While some oversized items may qualify for Priority Processing, they are not eligible for express shipping (Next Day Air or Second Day Air shipping).

The Priority Processing option is available on most items within and will be presented as an option only on items that qualify. If you do not see the option, ADD PRIORITY PROCESSING while on the shopping-cart page, an item in your shopping cart does not qualify.

Choosing Priority Processing does not guarantee that your order will be automatically approved. If, during our review process, errors are found or the credit card is declined, then the order will be placed on hold until the issues are resolved.

Priority Processing is only available for in-stock orders placed between the hours of 12:00 a.m. EDT and 2 p.m. EDT, Monday through Friday.

The option to add Priority Processing to your order will only be available in the shopping cart during these hours. If you added the option to your cart prior to 2 p.m. EDT, but had not submitted your order by then, you may submit the order up until 2:30 p.m. EDT. Otherwise the option will not apply, though the fee will be charged to your credit card.
