Yes wood is expensive you get it legally but if you have a forest 1-2 Km near your home the wood can be free. Like people own the forest, you can't cut any tree, you need to do a request and a person will come and mark some trees for you to cut (there are some criteria for what tree you can mark for cutting down). So then the expanse is cutting, moving and storing this wood .

On top of this there are people without jobs that can just cut unmarked trees.

Coal prices is also not the same in all places in the country, if you are closer to the coal source the prioce is lower because of transportation costs.
