4. Do you charge sales tax on product sales?

For deliveries to California and Florida destinations we are required to charge a state sales tax plus a local surtax.  The surtax depends upon the precise county or city of the destination.  Shipments to all other destinations in the continental U.S., Alaska, Hawaii, and U.S. Territories are not taxed.  The tax will be calculated after you place your order.

5. Does your company accept product orders from outside of the United States?

Yes. For the most convenience, please be sure to check with the dealer in your area to place your order (click the Dealers link at the top of the page); otherwise, contact us by phone or email in the USA for a quote regarding shipping charges. 

6.  Can your company ship to a PO Box?

Yes. However, your PO Box must be large enough to accept the product you are ordering.

7. How long will it take to receive my order?

Orders are shipped Monday thru Friday excluding holidays. Orders typically require approximately three to seven working days to arrive at domestic destinations from the time they are ordered.  You will receive shipping information with an estimated time of delivery for your international order.

8. Is there a problem if I have my order sent to my work address, the address of an institution, or a friend's work or home address?

Orders must be shipped to the address on the credit card to protect against fraudulent orders.  Contact us if you need more information about this matter.

9. How do I track the status of my order?

Order tracking is available through the Internet as long as this shipping option is specified at the time of purchase.  If an order confirmation is requested, when you complete your order you will receive an order confirmation number.  Depending on the shipping option, enter the confirmation number in the appropriate shipping website. Contact us if you have questions about this.

10. I forgot to add something to my order and I already have an order number. Can I call in and add it to the order?

Unfortunately, once we have the confirmed order, the order is immediately processed and readied for shipping. We cannot change the dollar total of the order. This is a requirement of our merchant bank to protect consumers from merchants increasing the order amount without customer consent.

11. Does your company ship to APO/FPO addresses?

Contact us directly to ship to APO/FPO addresses.

12. What is your policy on lost shipments?

If you specified a trackable form of shipping and delivery of your ordered product to the shipping address that you specified is not confirmed within seven working days of its shipment, we will send a replacement product to you or issue you a full refund including shipping costs upon notification of the lost shipment. Notification of lost shipments must be received by us within 30 days of the order ship date. If your shipment was lost, please contact us by phone.

Please note: We are only responsible for a package until the carrier confirms that the order has been delivered. If the tracking information we have for you shows that the order was delivered, but you have not received your package, please contact our Main Office. We will be happy to investigate the matter with the shipper, but we cannot credit orders if the tracking number shows the package has been delivered to the appropriate address (with or without signature).

We are not responsible for lost shipments if you did not specify a trackable form of shipping.

13. What is your policy on returns?

We warrant all of our ADC products for one year subject to the usual disclaimers for abuse, water damage, chemical damage, etc. Standard products may be returned and replacements will be immediately sent out.  The same warranty applies to our MCA products, however, many of these are often made to fit specific requirements or our customers in which case, they are repaired upon return.
