Shipping Information

We can ship products anywhere in the United States using UPS (big brown truck) and USPS (US Postal Service). When you place an order we will estimate delivery dates based upon the availability of your item(s), shipping method selected and your shipment's destination. Our shipping charges are determined by the total weight of your order.  We do have shipping options for International sales. However, some products cannot be shipped to international destinations due to weight or contents. You will be restricted during your order process if that is the case.

When can I expect my product to ship?

ORDERS PLACED BEFORE 1 PM EST TYPICALLY SHIP THE SAME DAY. However, this is not guaranteed and at times will not leave our location for 1-2 days if we have an unusually high volume of orders. Also, when there is an exception or backorder it may be the next day or two.

Occasionally a part will be shipped directly from a manufacturer.  We cannot guarantee a ship time on those items, but we will put a note in your order when we send you confirmation of it being shipped that it is coming from the manufacturer. We will give you a time frame to expect your part in that attached note.

NOTE: While we can't guarantee same day shipping, most products ordered will ship the same business day if ordered before 1 PM EST. 

How long will it take to receive my product?

When calculating your estimated delivery, there are several things to take into account.  Saturday and Sunday do not count as shipping days for UPS.  You skip those days when estimating.  You also skip holidays and days that UPS shows as closed in the delivery/pickup schedule on their website.  For instance, Thanksgiving, the day after Thanksgiving, Christmas, New Year's Day etc. are days that UPS is CLOSED for delivery. 

Counting starts on the day FOLLOWING the day the order SHIPS.  If your orders ships on Monday then your shipping day ONE is Tuesday.  You count each consecutive business day (no weekends or holidays) to reach your estimated delivery date.


You PLACE an order on Tuesday, shipping to California. California is a 5-6 day ship time from our HQ in Florida. If we SHIP your order on Tuesday, then you can expect your order on the following Tuesday or Wednesday. If we SHIP your order on Wednesday then you can expect it Wednesday or Thursday of the next week. Our website send an automated email when we ship your product and it will include your tracking number.

That same order placed 3 Day Select will reach you on Friday if shipped on Tuesday.  It will reach you on Wednesday if order is placed Next Day Air and we ship it on Tuesday.

That same order placed on Wednesday before Thanksgiving and SHIPPED on that same day (still going to California) will be delivered the following Friday or the Monday after that.
