We're talking about products here, not taxes. Instead of buying Tropicana, you can buy something else, or buy apple juice or water instead. If Tropicana increases their prices and/or product sizes and you continue to buy their product, obviously the price is not too high for you, nor is the product size too small for the price. If it were, simple economics dictates that you would stop buying the product.
And in fact, yeah, if you don't like the HST, you can move elsewhere, such as to the prairies or out of the country. Obviously there are other reasons why you would want to stay put that outweigh HST implementation, otherwise you would have been gone by now. It must not bother you *that* much.
