How much do you usually pay for firewood?
It's probably no cheaper than gas, BTU for BTU.
Chainsaws, also, are very costly at the moment. Hundreds of pounds for a basket case Husqvarna or Stihl, fifty pounds for a ten year old Poulan/Mcculloch/Partner sticker special, it's daft.
I was thinking spring may be the best time of year to haggle for firewood and saws... have you noticed any seasonality to ebay prices on these fine goodies?
