Our goal is to keep the ordering process as simple as possible. Shipping times vary from 1-3 business days and delivery time varies between 3-10 business days if your product is in stock.
Please read through this instructional guide so you can understand how the process works and what you should expect to happen once you place your order with us.
- You will receive an order confirmation email as soon as you place your order. This means that we have authorized your credit card for the purchase and are preparing your order for shipment.
- As soon as we receive your order, we automatically reach out to our warehouse to confirm that it is in stock and available for immediate shipment.
- If your item is on backorder or unavailable, we will reach out to you via email.
- If your item(s) are available for immediate shipment, we will process the charges and submit the order for shipment.
- If your order is stock and your credit card is approved by our fraud guarantee department, the product ordered will ship within 1-2 business days from the date of your order.
- We will send you the tracking information within 24 hours to the email address you provided when checking out.
- We ship daily via UPS Ground, Fed Ex Ground, and Freight to the lower 48 states. Most all orders will ship the same day as ordered if the order is submitted before 1pm PST (some exceptions apply, some part & freight orders may not ship until the following day).
- Some parts orders and freight shipments are subject to ship the following business day if the order is placed close to the 1pm cut off time.
- Shipping costs are included with any unit going ground to the lower 48 states. AK & HI ship by AIR at additional cost.
- We do not offer Cash On Delivery.
- A phone number is required by the freight company so a delivery appointment can be made.
- Failure to provide this at the time of order may cause a delay in delivery as freight items will not be delivered without an appointment.
- A delay in delivery may also cause additional storage fees to accrue that will need paid prior to delivery.
- Customs, Duties, and Taxes: Import duties, taxes, and charges are not included in the item price or shipping cost. The recipient of an international shipment may be subject to customs brokerage fees, import duties, and taxes after the shipment reaches the destination country. Additional charges are the responsibility of the recipient because we have no control over these government-imposed charges and cannot determine what they may be. Customs policies vary greatly among countries. Therefore, we cannot, and will not, offer advice about taxes in your country. We report the amount of the sale on the Customs form. Please do not ask us to claim less than the actual purchase amount. It is the customers responsibility to know the legality of the products ordered in their country. Do not order items that are illegal to import into your country. Laws are different in every country and we cannot keep up with them all. It is your responsibility to check with your Customs office to see if your country permits the shipment of our products to your country.
- As the buyer, it is your responsibility to find out that information before you order. Please contact your local customs office for information.
- To avoid a delay in receiving your order from customs, consider the following:
- Provide us with a phone number where you can be reached by customs when your product arrives. This phone number will be listed on the commercial invoice so customs can reach you to clear your order.
- Please do not refuse a shipment or ignore requests from carriers regarding duty and/or tax liability charges. Be aware that most carriers will hold a shipment for 5 days after arrival in your country before they return it to the sender.
- We do not refund original shipping charges for goods that are refused for delivery at customs.
- We will deduct all additional fees resulting from refused international shipments from your refund.
- If we are charged for YOUR taxes and duties on the shipment or incur any penalty or lawsuit related to your order or shipment, we will post the charge to your credit card.
- If the package is seized by Customs for any reason and we do not receive the package back, we will NOT issue you a refund since, obviously, local laws and regulations determine the fate of the package. If we do receive the package back after being seized, you are still responsible for the shipping charges and any other fees plus penalties incurred.
- We ship via UPS and FedEx for most products, USPS for small parts and accessories, and freight for large products.
- If you don't receive tracking information from us within six business days of your order confirmation, feel free to follow up with us at firstname.lastname@example.org
- Please inspect the packaging of your items when they arrive.
- If there are any products damaged upon arrival, you can file a warranty claim to get replacement parts for anything that's damaged.
- If your item(s) do arrive damaged, please send photos to email@example.com and we will process an insurance claim on your behalf.
Cancellations & Refunds:
- All orders canceled are subject to an administration fee equal to 25% of the total order amount, whether or not your order has shipped. This is a fee that covers administrative and personnel fees.
- If your item is on backorder and you accept the backorder, we will hold your payment until the product ships. If you decide to cancel before a backorder arrives and is processed for shipping, we will not charge a fee.
- If your order has shipped, you (the buyer) will be responsible for actual return shipping charges. Refunds will only be issued to the original credit card that you use when placing your order.
- From time to time, a product may run out of stock at our warehouse and the website wasn't updated when you placed your order. In that case, we will send you an email right after you place your order notifying you of the backorder, what the expected time for arrival is, and what substitutes are available in case you are interested in getting a product sooner.
- The expected arrival time may change due to unforeseen circumstances like a shipment getting held up at the port upon arrival or the factory missing a certain part needed to complete the manufacturing process.
- If the arrival time changes on your order, you can let us know whether you would like to keep the order, substitute for a different product, or cancel the order altogether.
- Once back orders arrive, we will notify you by email with your estimated ship date and you will receive an email with tracking information within 1-3 business days.

You can cancel your order free of charge up to 48 hours after the order was placed and if the order has not been physically shipped.
All unshipped orders canceled after 1 hour are subject to a 5% cancellation fee because we incur costs from our credit card processing company after we confirm your product is in stock and capture the payment for your order.
If your order has been shipped, the standard return procedure applies.
Refunds will only be issued to the original credit card that you use when placing your order.
We rely on just-in-time fulfillment from our suppliers to provide you with a vast array of products for sale at low factory-direct pricing. This allows us to cut the costs of overhead and middle-men and pass those savings onto you. Sometimes, products are so popular that they go out of stock before the next shipment arrives at our suppliers warehouse.
If the product you purchased is out of stock at the time you placed your order, we will notify you via email as soon as possible and give you the ETA as well as other options that are currently available.
If you can't or don't want to wait, you can choose an alternative product. At that point we will either charge or refund you the difference, update your order, and ship out the alternative product.
If you don't want an alternative product, you can cancel your order without any cancellation fee.
If you choose to accept the ETA and wait for your product, you order will be placed on pre-order status. This means we will place the pre-order with our supplier so that the product is reserved upon arrival and will ship out to you as soon as it arrives.
If you choose to cancel your order after you have confirmed your pre-order, and it still hasn't shipped yet (like in the case that it gets delayed further) then you will be charged the 5% cancellation fee we must charge to recoup the losses we incur from our credit card processing company when we issue refunds.
If you choose to cancel your pre-order after the product has shipped, the normal return policy applies.
