The terms "used to", or was...ing" or "were...ing" are expressed in Spanish by using a form of the past tense known as the imperfect tense. It is used to express actions in the past that were continuous or habitual over time, or for expression of moods.
In this case, you really need to know who is doing the buying for a definite answer. "I used to buy" would be "Yo compraba". "You used to buy" (talking to a friend) would be "Tú comprabas". The other forms are: compraba, comprábamos, comprabais, compraban.
The same expression "yo compraba" could also be translated as "I was buying". Again, context is king. This is why the same paragraph can be tranlslated by different people, and result in various interpretations.
