Wow, that's really cheap. Like Christy said, I would highly recommend checking out the history and reputation of the place first. If they're doing sales like this just to stay afloat in business, they could easily shut down in the next couple years and you'd be out your money and vaccines. You can't guarantee they'll be around for another 50 years, but even just feeling confident they'll still be around for the next 3 year's will make it worthwhile.
