Jolse is a an online beauty store in South Korea, and they are offering free express shipping on all orders over US$50 for two days (ends 25 Nov PST). Shipping is normally around US$15 to Australia. The last time I ordered from them it was shipped via DHL. They have very competitive prices for big brands like COSRX and Purito. They're also offering freebies and limited time deals. Make sure you grab the $5 off coupon if your order is above US$50.
The Purito Centella Green Level Unscented Sun 60ml SPF50+ PA++++ is one of the contenders in our best facial sunscreen under $20 poll.
If you're into K-beauty, this is definitely worth checking out.
