Long time lurker since 2009. Second deal ever posted so please be merciful.
Clearly Contacts have 20% off all contacts + free shipping on orders $99+ (CYBERMONDAY).
For glasses, they also have up to 80% off frames + extra 40% off lenses (FRIDAY40).
I'm not sure if you might also be able to use in conjunction with CashRewards/Shopback's 3.50% cashback (8.40% for new customers), but worth a shot.
It's not as good as the Specsavers $50 off $200 deal, but an alright alternative if you don't want to spend up to $150.
