Every Lube Tech gets this to start out with without spending a dime and what I’d recommend…

What I recommend is wait to see if you like the type of work your doing for a living. Use what they provide you with and don't be in a hurry to fill a cart with the same things they already provide you. You have time. Little by little build your collection at home with some of the basics to work on your own car and in time as you can afford add to it.
