Our postal address is:
Zandra Johnston
Box 1357
Portage La Prairie, MB R1N 3N9
Expect to pay $12 -$20 for most quilts.
If you have a small scale, a printer and web access we recommend Canada Post Ship-in-a-click
You can do everything at home and try out different packaging to get the best price. It includes $100 of insurance and provides you with a printable label that you can tape on your package.
We recommend regular parcel as Xpress Post and Priority Courier cost 2-3 times as much and don't arrive much sooner if at all.
Don't use a courier because they won't deliver to a PO box and they won't deliver to houses in the country. 
And remember ....
We pay the return postage
on quilt orders over $50. 
($10 charge for orders under $50)
