    Q: かばんはかいましたか。
    
    A: 1.　はい、もう **かいました** 。  
     　2.　はい、もう **かってあります** 。
```

Both answers also correct, but when should I use the second answer?

question
grammar aspect
Usage of Verb て-form あります
1. かいました I bought
  2. もうかってあります I have bought

First is past tense. Second is present perfect tense. You would use the
present perfect tense if you want to stress in the present time.
