Booked a course in Florida online with GolfNow. Received a confirmation that my card would immediately be charged $2.95 - which it was - and the balance of the fee paid at the club when I arrived. The course charged me the full price and GolfNow game me some vague explanation that it was not their responsibility.
Instead of booking through GolfNow I would recommend using them for research but book directly with the club and same a couple bucks.
