SHIPPING + ORDERING

You can E-mail an order to us HERE. Or call +1 (250) 769-1834 There is no minimum order here, BUT, there is a minimum shipping/handling charge to ship by Expresspost (airmail insured) or small packet. You can see all charges in the FAQ section. Please do not ask to ship uninsured as it merely tempts fate in an unwanted way.

Parts by the Foot! CLICK to see!

Prime Electronic Parts by the Foot! Transistors, LEDs, Rectifiers, Capacitors, Chokes and Diodes, as little as 8 cents each! Great deals on popular service and experimenter's parts, now you can buy them the way large manufacturers do, in bulk tape and reel, at rock bottom prices. These parts are sold by the foot. Yes, we are metric in Canada, but this is really the appropriate size for most people, and 30.48 cm just doesn't have the same marketing ring to it!

0.5kg of Goodness CLICK to look INSIDE the Bag!

Wahoo, Electronic Grab bags are BACK! We keep accumulating miscellaneous parts that are extras, come with bigger lots, and are being purged from our stock. At the same time, many people grumble about paying the minimum shipping charge when they ship something small. Well, we have the technology to solve this problem. We will add a 0.5kg (roughly 1 Pound) grab bag of new parts (mainly, there might be the odd pulled or used but useful item) to fill up the extra weight in your shipment! Some of the material is pretty spectacular, you will certainly get good value for your money. They include resistors, capacitors, ICs, chokes, semiconductors, switches, assemblies, and all kinds of mystery items, NO TWO BAGS ARE ALIKE. We have four categories, electronic parts, mechanical/hardware, vacuum tubes (will be some used types in every bag), and connectors/cables. Any type, US$15.
