If it's only 25 trips and the bonus is around 60-70 dollars within 4 days. Go for it.
55 trips in 3 days sounds a little much.
My current promo is 55 trips for 65 dollars. I simply laughed and planned on studying overtime at school to skip work because of how insulting it is...Like they think I'm stupid enough to do that many trips in 3 days just to add a dollar for every ride. Yeah right.
