S & H costs.
This is an illustrative guide-line sample case:

Handling:
For our S&H, we utilized a small S&H local business nearby, run by a single parent. She provides a reliable, prompt and affordable service.
For a typical one box, the handling cost is 1 hr labour, $20 for her time and travel expense to and from supplies stores, the lab, and the post office.
Material cost is approx. $6 for a box and $3 for wrapping material, a total of approx. $29.


Shipping:
A 3.5 kg box containing 6 glass jars of dog supplements product: 
The box, to allow for item protection wrapping,  is about 15 "X 11" X 7"
With $200 insurance, a required signature upon receipt, tracking number, and expedited service, withing the province, is under $30 shipping/postage cost.

Shipping cost of lighter and smaller packages, e.g. pills, would be less.
Some products are currently available overseas. They be be shipped to Canada, USA and other countries at the client's "shipping" cost.
