The first comment I'll make and underscore was made by Ms. Savage from the independents the other day. She said that in fact, while the administrative treatment of the product on either side of the border is different, the product is not actually essentially that different. It's the administrative requirements that cause the difficulties in moving product across the border, but the product specs actually are not that different at all.
In terms of why there would be a price differential between what is sold wholesale here and what is sold wholesale in the States, that is a function of what the market is going to bear.
