Similar Makeup And Color?

Well M.A.C. Liquid foundation nw15 looks really well on me. And it covers my acne very well. Image may be NSFW.
Clik here to view.
But thing is, Mac makeup is getting a bit too expensive and I can’t buy it anymore. Even if I buy it on amazon or eBay. Soooo. Is there anything cheaper that will cover my acne well? And tell me the color that’s similar to nw15 too ! Because ill be shopping on eBay
For cheaper stuff. I really can’t afford that much anymore.
