Well there's a variety of ways to answer that...Can you buy a heater? Maybe you can!

Do they sell heaters in any stores nearby? If not, can you buy a heater and have it delivered? Do you have money to buy a heater? Do you live in some sort of arrangement where you don't really have autonomy or what others might call, free will? Is there a person or group of people that are actively working against you, that would thwart your attempts to buy a heater?

So, maybe you can, maybe you can't.

This will be one you'll have to answer yourself I'm afraid. But I personally think, that you can buy a heater if you are so inclined. 😎
