1. Do you find that people are more willing to go for a credit card with a 1:50 chance of any given purchase being paid for over a 2% cash back card? Do you feel that people do not realize that they should "expect" about 2% cash back equivalent from those odds?
2. Have you had situations where someone winning the $2500 prize (split among all winners) is paid out more than someone winning the $3000 prize? (this happened in simulation a few times for me)
3. Is it possible to find out how many tickets are in play for any given week?

3) I hope you wouldn't mind my wild guess here - you did say that it's not unreasonable to expect that someone will win the 10m prize within the next couple of years, which implies about 79 million tickets in play per week? If it were only 9 million tickets in play per week it'd be about 18 years before a win would be expected. Since the prizes are split, it's difficult to know expected winnings (and therefore savings yield) without knowing how many others are playing.
