Animal Hospital of Peak Plaza is great. I see Dr. Szymkowski (spelling?) and I know Dr. Bailey is great, too. So either of them I would recommend. However, I think their prices are pretty much the average going rate around here, which is not really cheap. They are certainly not higher than average, and the care is above-average, especially in terms of them fitting you in and calling you back, the doctors calling to check on your pets, etc.
Someone suggested PetSound in Cary as having better prices and a great doctor but I called them to ask about some prices for a dog I am fostering and they were very busy and didn't call me back. So, maybe they are cheaper and good but if can't get a hold of them, that's not great.
For vaccines, look on craigslists under pets for "low cost care" or call the SPCA or Wake County animal control and see if there are clinics you can go to for those routine things. That can be a lot cheaper. You could get those out of the way at a clinic then establish yourself at a vet with the wellness exam.
I just did a super-quick search and came up with these links. They probably focus on spay-neuter but have vax, too. You can check them out:
-- for example, that one clinic says heart worm testing (I know that's done for dogs, I have no idea for cats) is $15, whereas at a regular vet it is $40. That just give you an idea of the potential savings, especially since with two animals it will all be times two.
