Shipping & Returns


We can ship to virtually any address in the world served by UPS, FedEx and US mail. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.

When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.

Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, total package weight will be rounded up to the next full pound.


You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

All returns are subject to a 15% restocking fee.  PTC TechBooks and TechGuides, and the Ness Visual Dictionary are not returnable.

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

If you need to return an item, please Contact Us with your order number and details about the product you would like to return. We will respond quickly with instructions for how to return items from your order.


If your package arrives damaged, note in writing the extent of damage on delivery bill (i.e. carton wet, crushed, torn, hole in carton, carton rattles, etc.)

If damage is discovered after delivery:

  1. Retain all merchandise, cartons, and packing materials for inspection.
  2. Notify local office or carrier (mail, UPS or motor freight) and request an inspection.
  3. This initial request may be verbal, but must be confirmed in writing.
