Visiting the US, buying data to use

Is it possible for me to obtain a SIM from an AT&T store and add data to it whilst I'm visiting the US? (Is there a plan which allows me to do this?) This would only be temporary (less than 30 days). I have an unlocked phone.This would be a huge advantage to me, since it avoids roaming costs.
