I think a lot of store will be on sale this weekend. Drive your car and buy things you need, especially those originally don't tax things.
It's unfair to take people's money out and benefit to the enterprise. But little people is so week and can't defeat those politician.
Any way, I can imagine the screen that more store might reduce revenue because people don't want to buy things in BC. They would like to drive across the border and buy thing in Washington in US. No extra tax will be issued. Perfect isn't it?
