My most concern woud be the overcharged tax. there was, I bought an item at www.jr.com for about Cnd$130, and I was charged about Cnd $50 for tax. it was much higher than the tax in here ontario, which is 15%. It was shipped by UPS ground. Now I want to buy a computer being sold exclusively in U.S market, say it's Cnd $2000, I probably will be charged Cnd$ 600-800. How do I avoid the mad charge from shopping at an online U.S store has no botherfree policy? will it be helpful to choose a shipping method other than UPS ground(I heard a lot of people got caught by it)? What's your experience?
