Assignment: Online shopping in Canada and the U.S.

I want to buy some specialized camera equipment. I want to figure out if I should buy it from an online store in Canada, or from one in the states.

I need:
1 Canon EOS 7D camera body
1 Canon 50 mm f1.2 lens

1. Find the items at www.vistek.ca. Add them to your cart to find the total price after tax and shipping. Enter fake shipping information, and choose "bank draft/money order" as the payment method. Print the cart page, showing this total. (Don't submit the order!!)

2a. Find the same items at b&h photo in NYC. Check out as a guest, and enter fake shipping information. Print the "payment" screen, where your total is listed. (Don't actually buy these things!!)

b. This amount has to be converted to Canadian dollars. The exchange rate is $1 USD=$1.03 CAD. Find the price in Canadian dollars.

c. You will be charged both PST and GST at the border. GST=5% and PST=8%. Find the amount of each tax.

d. Find the total price for these items purchased from B&H, including exchange, GST, and PST.
