Getting low

[Quang Hai]

Hello everyone. I am here again with another question.
When a person says they buy something, butter for instance, because 'they noticed the butter is getting low' Is that means in their house there is not much butter left or it means they noticed that the butter price is lower than before?
thank you!

In your example, 'the butter is getting low' means there is not much butter left. There is no context to make you think of price.
However, if your friend had recently been discussing buying company shares and then said, Coca cola shares are getting low, you could probably assume they are referring to the price of the shares.
