I saw a local sign of someone selling firewood in bulk, 1 "raummeter" ( 1 cubic meter, or 1 m3) cost 170 CHF. At the local Coop it costs 8 CHF for a small box of 0.042 m3. If I divide 1 m3 by 0.42 m3 I come up with 24, meaning 24 boxes of Coop wood would equal the one large "raummeter" selling for 170 CHF. 24 Boxes of Coop wood would equal 24 x 8CHF = 192 CHF. So as far I see, there's not really any advantage of buying wood in bulk (well ok, a very small savings of maybe 10% or so).

Usually in other places I've lived, buying firewood in bulk is substantially cheaper than buying boxed wood at the supermarket, but here it seems to be about the same price. Or am I calculating this wrong, or am I missing something?
