Now your asking tricky questions! Lol. I think once the box exists it will be fairly simple. A 1:1 exchange for what you take out I think and take what you want as long as you post pics of what you got. But how did they start the box in the first place? Did a group of people mail some items to start the box? That's my big issue. So right now I'm just looking for those who would be interested. Looks like there might be enough people so I guess I need to look into the finer details.What are the rules?
If it was being shipped from B.C to say Ontario it would cost double what it would only going a few provinces over. I'm not sure what postal codes you used for the $18 estimate?
Anything going from Ontario to B.C starts around $14 as the basic minimum, and anything going within province or next province over starts around $9 basic minimum...I work at the postal outlet in the mornings at work and it is cheaper to mail things to the states than it is to mail within Canada!
