Classifieds: Split the Shipping?

I'm going to be ordering the two belts for my chiclet PET cassette drive.  Adding an extra belt or two won't increase the shipping cost, so we'd be splitting the shipping cost.

Or if you know of a Canadian source?

A buddy directed me to Banggood in China; I bought an assorted bag of belts for < $5cdn.  I'll update this when they arrive.

In the meantime does anyone know the diameter or circumference of the drive and reverse belts?
