Drugstore brands like Revlon, Maybelline, Cover Girl are non- prestige. Mid end brands like Smashbox, Urban Decay, Tarte, Stila are prestige. They usually have a list posted by the front registers. The only time prestige gets 20% off is if you get a promotional mailer in the snail mail. It will specifically say "no exclusions" or it may exclude fragrances, high end skincare and Lancôme only.
