Hi Lex
I've started beauty training about a month ago, and I can choose whether to buy from the school or from suppliers. I did buy some from the school but I also like to look at individual suppliers to see the products in the kits. You should ask for a detailed kit list- eg not just ''wax kit'' but ask what exactly they want you to bring for the course or you need to do case studies. They may tell you wax heaters are provided in the class but you will need to have your own to practice at home. Kits vary alot and I choose what I feel is best for ME (affordability, the product appeals to me e.g. ingredients, etc). I have signed up to alot of suppliers and requested catalogues and then go through them to decide what I want.
Not all companies will give you a discount as a student, or even sell you products and some have a delivery fee or say you have to buy a certain amount of stock (especially skin care products) or pay for delivery so this affects my choice too. I recommend Salonserve and Salons Direct as I've ordered kits from them. I've read many glowing reviews on skin care products (like dermalogica) but then you can't actually buy them if you're a student/mobile or starting up as you cannot get an account or meet the minimum order requirements. You really need to dig around to find what you can actually buy sometimes! Good luck ; )
