The two muni's in my city both are listed on GolfNow, but show the "mulligan" when you click on them. The dropped GolfNow because it wanted too many of their tee times. I suspect many of the courses showing the "mulligan" designation have done the same thing. Last year I saw occasions where you could get 18 holes & cart for less than $9. Prices that low might have caused them to switch services.
