SAVE 20% with code CL20OFF plus free delivery.
Just ordered 4 boxes of contact lenses online totalling $204 before coupon.
CL20OFF, though marked expired in recent posts, worked as described. Some people have mentioned receiving this code targeted in an email after not ordering for a while. For reference, my last order was just over 6 months ago. Also reported requires min spend $200.
AMS30 is still valid $30.00 off $119 plus FREE standard delivery.
(see comments from Jay408)
If above codes do not work, there's 10OFF over $99 listed at top of Specsavers site at time of writing, or $30 off with the usual automobile club membership.
Tax invoice available from account - order view for instant claim back from applicable private health insurance.
