I'm having trouble figuring out how to suggest two different scenarios. The question on my homework was "What can you do with $300?" I am looking to say something along the lines of "You could buy A, or you could buy B", as in, you wouldn't be able to buy both. So far, I've seen あるいは, それとも, and どっち, but I don't know if these are usable in this context. Any help would be greatly appreciated.
If you are applying the same verb to both actions, as in your question, then you can just join the objects together with か, e.g.
You can buy A or B.
If you want to use different verbs e.g. "You can buy a cat or deposit your money in the bank" then I'm not sure I know how to do this. I have asked a separate question.
