Deciem is offering free shipping with no minimum spend for a week across their sites, which is handy if you just need one or two low price items. Skincare items start from $7.20. They also have primer, foundation and concealer and hair care including their new shampoo and conditioner.
I have been using The Ordinary skin care products since their launch and can highly recommend the products. You won't get better bang for your buck in terms of active ingredients, but they are minimalistic - so don't expect luxurious creams or fragrance. If you're not sure where to start, check out their regimen builder.
Products are rarely on sale (only once a year at 23% off in Nov in recent years), and often exempted from cashback when buying from retailers (looking at you, lookfantastic.com!).
Did you missed out on the 20% off the ordinary @ Myer online a few days ago
I stocked up on some serums
