You can find a cheap alternative to almost any high-end beauty product out there (except for this little beauty). But sometimes, it's just better to splurge. We asked TotalBeauty.com readers what products they buy on the cheap and which they just won't compromise on. Check out what they had to say and join in on the convo here.

"I find that after using Benefit, Dior, Lancome and many expensive mascaras, my all-time fave is L'Oreal Voluminous. I paid $7.50 as opposed to over $20. And since they say mascara should be replaced every 3 months, I think it's worth it." -- canuckinla

"If it goes on my face, I shell out money. My skin is extremely sensitive. I've tried numerous brands, both expensive and cheap, but the only thing that doesn't irritate my skin is Clinique." -- ama1221

"I definitely save my money for good moisturizer! I have dry skin, and a lot of things don't work for me. I skimp on cleanser (Cetaphil); I splurge on my nighttime moisturizer (La Mer) but skimp on my daytime moisturizer (Cetaphil moisturizing cream and Neutrogena Dry Touch Sunblock)." -- ang093006

"Funny story: I lost my favorite Bobbi Brown powder blush and I do NOT step out of the house without blush. So I went to Target to get something cheap to hold me over until I could go to the Bobbi counter. I was about ready to give up until I spotted the perfect shade from, of all the brands, Wet n' Wild! And you know what? It is just as flattering and has twice the staying power as other blush for less than $2!" -- carbonparadise

"I splurge on everything!!!! lol, I know that I shouldn't but I buy anything expensive that I possibly can, I love buying makeup, it's actually my hobby, and the more expensive, the more fun." -- kaiti_marie
