It is our goal to ship any orders placed before 11am (EST) on the same day and it is our guarantee that all orders will be shipped by the end of the next business day after being placed.

We currently use the following carriers for orders placed at UPS and USPS. Unless the shipping method you choose states which carrier is to be used, we reserve the right to use any of these carriers.

If you require a specific carrier to be used or a specific carrier to be avoided for your order, please call the office on 866-537-7383 and we will do our best to accommodate your needs.

If you select a shipping method at the checkout which states the number of days delivery will take, please be aware that this is an estimate and it is possible your order takes fewer or more days than stated to arrive.
