"You sure you don't need an astromech? R2-E7 here is a real bargain!"
―Unknown droid merchant[src]

R2-E7 was a R2-series astromech droid. A droid merchant in Mos Espa once tried to sell this droid to Anakin Skywalker when the young Jedi visited the planet Tatooine in 21 BBY to investigate rumors of a new kind of battle droid.
