NAVIGATION: To make your life easier, and help you find exactly what you want, we have broken the on-line equipment catalogs into smaller sections. Just CLICK on the item you are looking for at the left, to see the matching catalog. Large graphical catalogs are a bit SLOW, so please give them a bit of time to load. The top header of each catalog is largely the same, so don't think you are stuck in one place!
You can order anything here just by picking up the phone, and calling (250) 769-1834 during normal office hours, 8:30AM to 4:30PM PST, OR, Email your order to Susan HERE.SHIPPING: Preferred and Alternate Methods CLICK for FULL DETAILS ON OUR FAQ Page. Rates are now changing rapidy, often with little notice to us, so all the data has been transferred to the FAQ page for speedy updating.
E-Mail Susan if you want a quote for shipping to other destinations, or for something heavy. Sorry, we can't safely send most individual small parts in a regular letter envelope, they get destroyed by the automated handling equipment. Sometimes we can ship very rugged parts in a small padded envelope by letter post. Ask Susan.
There is a packing charge for large or heavy equipment, see the FAQ for details.
If we have your valid data on file, you can just click on the ORDER email link to place an order and indicate your approval to bill, and we will do the rest. We keep your active information for ONE YEAR for your convenience.
If this is the first time you have dealt with us, you can phone +1 (250) 769-1834 to supply the billing info, or send it by the email link, as you prefer. We accept VISA/MC, international money order, Paypal (to Susan@Okanagan.net), and bank wire transfer. Please note that there are transaction fees with Paypal and wire transfer payments, the wire transfer fee is frankly horrifying.
