We ended up buying 20 cube from a village local.
Apparently, there are chaps who work for the forestry managers. They receive no money as wages but are allowed to take as much wood as they wish. The wood they remove is 'waste' wood as far as the managers are concerned and consists mainly of older, dead wood and it's all hardwood, mainly oak. It's perfect for burning as it's dry and seasoned.
At 40 lev/cube, delivered, we weren't letting that chance pass.
It's entirely possible that most villages have people working under the same rules, i.e. no pay but lots of wood.
