"4 for 3" offer on AMO Oxysept 1 Step until 30 June.
£23.95 for 3 months, this retails at my local optician for ~£27 for the same pack.
I've typically bought 1 years supply for around £90 for each of the last 5 years or so and never seen the price as low as £71.85.
In stock as I've just ordered.
Note that this is without the LC-65 cleansing solution supplied in alternative packs.
