If you missed out on the 1/2 price Olay at Woolworths last week, you can still get 1/2 price at Coles this week. Starter packs are included but not gift packs.
Olay is also half price at Chemist warehouse (ends today 6 Dec), 40% off at Priceline.
If you're looking at the Olay Renegenerist day and night moisturisers, a better deal would be to get the Day and Night Gift Pack at Priceline at 30% off for $31.50, as both the products still add up to $49 when purchase separately at half price.
What's the difference between the Serum and Moisturizer?
