We (
o-store.ca) are indeed selling them. You can find the list of models we carry
here. Unfortunately the shipping cost might still be quite high as they are all quite bulky and decently heavy. We will have them for sale at the WCOCs and COCs in Alberta in August if anyone is looking for one but wants to avoid shipping costs.
edit:
I should clarify - when I say "quite bulky and decently heavy" I mean in terms of getting them into a box for shipping. Our largest bags carry 40 and 45 litres and weigh about 3 kg due to the aluminum frame for the seat. The extra weight due to the frame is far outweighed by the benefits of having a seat attached as far as I'm concerned.
Shipping should be between $25-$35 for most of Canada and about double that for shipping to the US.
