I just bought some Indie samples from My Beauty Addiction and Femme Fatale Cosmetics!
I really like that many companies provide samples.
I fell in love with Prettymaking's swatch of Desecration from Femme Fatale Cosmetics and I had to check out the store. They have some amazing colors!!
Here are the samples I purchased
From My Beauty Addiction $8.50 for 10 samples
The website doesn't offer samples for some reason (or maybe I just couldn't find it) but her Etsy store does.
