You do have to bear in mind though MArk, that the reason places like VetUK are so cheap is that they have less overheads and can also buy in much bigger quantities than a small vet can, partly due to space, and partly cos they are reaching a wider market, and things like Seraquin aren't widely used, so vets might only buy a few boxes cos they might not use it that much, whereas VetUK will buy a lot more.
