The main thing was the cost, and if that thing you said to sign up for saves a lot, I'll definitely do it.
But I did a rate quote from my postal code in alberta to one in mississauga (just happened to know it off hand from immigration stuff) and a 5oz package was $13 - which is bad enough, but then boxes that were 1, 2, and 3 lbs only cost $2 more.... I can't imagine anyone buying a bar of soap if they have to pay 2-3 times the price of it in shipping. 10 bars, maybe, but not a single bar. Now, even if it's half price with that discount, that's still 6.50, STILL more than I'll charge for an average bar of soap.
