I have given up finding good travel sizes except for tooth paste. I purchased a set of 4-3 oz bottles (different colors so I don't have to write on it) in their own handy-dandy bag from Walgreens. Cost: $3.99.

Love those TSA rules! I lost a couple of tubes of sunscreen that way and gave up trying to explain that they were 1/2 empty. Gee, I have no idea why they didn't believe me.
