I love makeup. A little too much.
I tend to make most of my purchases online: Sephora, Beautylish, NAP, Nordstrom, NM, direct online retailers.
Occasionally I buy at Ulta and Target. (probably 4 times a year)
I'm not a big fan of testers. They skeeve me. I may test certain products on the back of my hand to get an idea of consistency or pigmentation, but otherwise I read up on reviews beforehand and/or cross my fingers.
