Marm is in Canada, eh...shipping costs are double that of the lower 48 usually - unless your talking Lil Brown, then they are five times the cost of shipping in the lower 48.
In addition, if a Canadian brings in more than $20 worth of, or 200g total weight of tobacco, they have to pay a 300% tarriff at the border; so that $40 order becomes $120...so ordering in bulk isn't always the greatest idea!
Pipe-smoking in a Commonwealth nation is all about either paying through the teeth, or massaging the system - and most of us choose the latter, which somewhat limits the etailers we can deal with.
