What are the differences between these sentences?
It would be great if you bought some apples too
It would have been great if you had bought some apples too
It will be great if you buy some apples too
I would actually like to know to which particular situations each of these sentences are appropriate.
Which of these are the most suitable for a situation such as this: I've just returned from the market and my brother says: "It would be/have been great, if you bought/had bought some apples to"
