Answer- Loose-filled bulk bags

The large 1.6m3 bulk bag is the most cost-effective purchase, although you can buy the 1.2m3 bulk bag or 0.8m3 bulk bag of kiln-dried logs, which will work out more cost-effectively than the other firewood options. 

If you do not wish to have firewood delivered in a large bulk bag, you can also choose to take delivery in small bags, either 80 bags on a pallet, 50 bags on a pallet, or 30 bags on a pallet. Some people find these easier to manage and handle. It’s really down to personal preference as to which suits best.
