かえます or かえません?! Are these even words?
While studying my notes I have かえます as meaning "can buy/able to buy" and かえません as "can't buy/not able to buy" but when I look these words up they do not appear. I translate my notes from audio lessons so the problem is probably that they are not properly transliterated. Any help would be appreciated :)

Answer

As you are mentioning, this is the potential form of the verb to buy.

買う "Kau" infinitive
買います "Kaimasu" ます form.
買えます "Kaemasu" affirmative potencial form
買えません "Keemasen" negative potential form
