Cherry Culture: 20% off all orders over $50. Offer good July 3 through 7. Use code GR4S.
Nonpareil Boutique: 20% off site wide. Offer good through July 7. Use code ID20. I love this site. Their everyday prices are already ridiculously low (NYX round lipsticks $1.90, Mega shine gloss $3.98), and that's before the 20% discount!
And although Ms. CuppyCakes doesn't have a sale advertised on their site, their NYX round lipsticks are everyday priced at just $1.25. Their other NYX products are offered at great prices as well. P.S. If you're not familiar with Ms. CuppyCakes, they exclusively offer NYX cosmetics, Red Cherry Lashes and also have an extensive selection of natural hair brushes on their site.
Aromaleigh Mineral Cosmetics has many items offered at 25% their regular price every week.
