You need to log out and back in, or at least start a new authentication session as yourself, to pick up the new group memberships. Run the "id" command with no arguments to see your current group memberships. You'll see that "sudo" is not one of them. Now try "su - rprice" to open a new session as yourself, in the same terminal. In this new session, if you run "id" with no arguments, you should see the sudo group listed.
