Ours is $25 for a check-up or if the dog is sick.
Vaccines are $7 a piece, any other meds you have to pay for.
If you take your dog to the vet and it is sick, they charge you the 25 the first time you go in, but any visit after (say a week later to make sure all is alright) is free.
We (Kona and I) love our vet... there are three in the office, and we like the two we have met. The techs are very nice as well, and gentle with your animals!
