Hey, I just tried the Shoppers Drug Mart "Summer On Game".
If you play the game, you get extra chances to win 1 million points. The game gives you 20 questions, thus you can gain 20 more chances to win the 1 million Optimum points.
But just to make it a bit faster, I started with answering one question, and then copied the www address and opened up a second page. I would then use that page to answer the second question, and continue to alternate back and forth.
At the end, it says congratulations, you have won all 20 chances.
However, at the top of the page it says that I have earned 40 chances to win.
It seems as though having two pages open, doubled my gain ???
