A: There are actually quite a few nice foundations and tinted moisturizers that look fresh and pretty, and won't lighten your wallet too much. Here are a few that I like.

Under $30
Prescriptives Unmakeup ($25)
MAC Hyper Real ($24)
Calvin Klein Sheer Coverage Foundation SPF 20 ($29)

Under $20
Neutrogena Healthy Skin Liquid Makeup SPF 20 ($12)
Oil of Olay All Day Moisture Stick Foundation ($11)
5S base color ($15)

Under $10
Maybelline Express Makeup Three in One SPF 15 ($9)
Maybelline True Illusion Makeup SPF 10 ($8)
Cover Girl Smoothers All Day Hydrating Make-up ($7)
Max Factor Seamless Stick Makeup ($8)
Kiss My Face Naturally Tinted Moisturizer SPF 8 ($7)
Wet 'n' Wild Twisted Creme Foundation ($2.99)

Be sure as you are choosing a foundation that you pick a shade that matches your skin exactly - not too dark, too light, too pink, too orange. Rely on testers or at least a liberal return policy at the store in case the color or formula is wrong for you.

Good luck!
