Which is better?　私は買いましょうか？ or 私が買いましょうか？


I am trying to say: "Shall I buy it?" Which would be better?

私は買いましょうか？ or 私が買いましょうか？




Instead of answering which is better, I would like to write some opinion. If
in the situation here,

> Shall I buy it?

" **I** " is not that important (the person you are talking to, knows it is
about " **you buy or not** ", not "who to buy it"), I suggest 買いましょうか{かいましょうか}
/ 買おうか{かおうか} / 買っちゃうか{かっちゃうか} ... which means you wish to have some feedback /
you are considering buy or not youself (but saying.. hah)

Apart from " **shall I buy it** ", you are actually asking the difference
between は and が. Let's keep discussing if you still have problems :)

一緒に頑張りましょう (look here, you don't have to say
私たちが{わたしたちが}一緒に{いっしょに}頑張りましょう{がんばりましょう})




Assuming you mean "Shall I buy it?" in the sense of **offering to buy
something** (i.e. "Do you want me to buy it?" or "Shall I be the one to buy
it?") then 私が買いましょうか？ is best.

If "Shall I buy it?" is wondering to oneself "Hmm... shall I buy it?" then
neither. That would need a completely different phrase to the two offered in
the OP.
