Clearly is offering free shipping on all contact lens orders until Sept 30, no code required. They're one of the cheapest places to get contact lenses online and you are able to claim the costs against major health funds.
Use code CLEARLY10 on orders above $99 for $10 off.
Those with large orders above $199 should use THANKYOUCL25 for $25 off.
I don't believe you can claim on your private health if using Clearly.. can anyone confirm?
