Maybe check the availability of some of the online glasses suppliers. I've bought glasses twice from ClearlyContacts out of Vancouver. It's never as cheap for progressives, which may be what we Canucks call your 'varifocals', and my first pair wasn't as good as my second, which I think had to do with a different shape of lense. But they weren't bad, and at a savings of several hundred dollars! I'm currently musing over offerings at Zenni Optical, another online supplier. I figure if I can find a good enough price, then it's worth the risk...
