Same thing with spare parts. Need a funky USB to USB cable at a precise length? Someone from China on Ebay will have it.

The "free" shipping time can take 3-12 weeks to Canada. So I always buy extra and re-sell them on Ebay to recover my costs.

I have 4 micro-businesses for beer money of spare parts people are willing to spend an extra $5-10 to get in ~1 week.
