>I work in a shop and I always laugh when people buy lottery tickets because the jackpot has hit a certain amount. Like ugh, $150 million, not even worth winning, but $200 million is.

It is a great way to self moderate your spending on lottery tickets while still getting that "if I won the lottery" feel. If there is 52 draws a year and the jackpot goes off enough for it to only hit (say) $200m+ for 2-3 of those draws then you go from potentially playing 52 times a year to just 2-3 times a year.
