These are a great deal for prescription glasses. I need the 1.67 index thin lenses and this is the cheapest I could find anywhere - $100 total cost. Even cheaper if you don't need the thin lenses.
Shipping is free over $125 or otherwise $10
Can pick up in store for free in VIC, NSW & QLD
They are good. Have been buying them for past 5 years.
