SUPER22MSE
Useful for people who don't have health insurance that includes prescription glasses. I have ordered from this company before while I was in UK. They do take a few weeks to ship.
There is a current offer of £22 for SuperDry frames. For lenses I wouldn't go with the free lenses - there are 4 higher grades (£9/£19/£59/£125) - the £59 package is more than enough for general use. You can also add tint/polarise/transition.
Just get your prescription from your optometrist - ask them for your PD if you are not sure.
Shipping is £8.33 worldwide. Hopefully won't attract GST from Australian custom.
