It looks like Chemist warehouse has 1/2 price on La Roche-Posay Athelios sunscreen range. Not sure when this went on sale but it wasn't in the catalogue. This is the lowest price I've seen for this very popular sunscreen.

The linked product is their most popular facial sunscreen, designed for normal, combination and sensitive skin prone to sun intolerance, is fragrance-free, paraben-free, non-comedogenic. It also comes in a tinted version

For other skin types:

Those with oiler skin types may prefer the Anthelios XL Dry Touch SPF50+ Sunscreen For Oily Skin - untined or tinted - $14.96

Those with dry skin types may prefer the La Roche-Posay Anthelios ULTRA SPF50+ Face Sunscreen For Dry Skin 50ml- untinted or tinted - $14.96
