I love NYX makeup - it's affordable and cruelty free. There's such a great range of products to choose from, my favourites are the lip butters and eyeshadows. The website is easy to navigate and you can search for all the products & prices on there, however you cannot buy directly from the website in AU. It directs you to the Priceline website, which is no problem and super easy to use, too.
The quality of the makeup is incredible, especially considering the low prices. Overall, one of my favourite makeup brands.
