Can't remember the prices (but it's very reasonable and if you book both 2 weeks apart you get extra off), and our vet gives a 10% discount for treating 3+ animals at the same time.
The boys had their myxi a few weeks ago, with full health check and nail trimming (no extra charge for cutting nails on all 4 of them), and then when they had their VHD last week she went through the full health check again - ears, bums, fur, teeth etc.
