Both of my girls had their CGC certificates. You mentioned PetsMart. Are you going to take your new dog to PetsMart for their obedience training? The reason I ask, is because as part of their second class (not puppy class) they give you a CGC test, and if your dog passes you get the certificate. So if you are going to sign up at PetsMart, you may not have to go anywhere else for the test.
