Building your kit costs money, a lot of money! Not only do you need a choice of products such as foundations, eyeshadows, bronzers, blushers etc you also need to invest in skincare, disposables, kit bags, makeup brushes, the list goes on. A good way to start building your kit is to sign up for pro discounts.
Did you know many Brands offer Pro Discounts available for trained Artists and students? I couldn't build my kit without these. They range from 10% up to a massive 40%, they are worth applying for.
You do need to prove that you are either a working or Student Artist with evidence such as Insurance, Website, Certificate of your training and often some form of ID such as passport or driving licence. Some are easier to apply for than others and some require less information.
I have put together a list of the ones I use for my kit with some others that may be of interest. These are for the UK but I know US offers many more.
