I'm with shopgirl. A nice $8 bottle of Pinot Grigio from Whole Foods or a bottle of Jose Cuervo from Specs makes me happy.
For the nonliquor I love new eyeshadow from sephora. My latest one is a cargo duo called corsica. Very pretty and summery and under $20
Philosophy 3-in-1s are great also
Luna bars while shopping
Lemon Crumble bars from Starbucks and the new banana mocha frapp lite (minus the coconut and w/o whip). yummy
