I say thats a pretty good deal really, all you can find at a retail store is the sawdust chips, typically $5 for maybe a 2-3 pound bag. If you want chunks, you have to find another source, like me.
Even I sell Alder and Maple chunks for $10 for ~10 pounds (see my post under SMF classifieds). Yes some people have local sources for wood, but if you're in Florida or Texas, and want some alder, you're just not going to find a "local" source.
The harsh part is the shipping for another $10, but heck that's the post office getting the money not me.
For $10 and a $10 pound box, I figure it takes me a bit of time to cut it up into hockey puck sized rounds, box it, fill the open gaps wood spaces with sawdust chips, take it to the post office, all for $10, then you have to have the wood in the first place.
Trust me, nobody is getting rich doing this, but I like to share wood with my SMF buddies. I can't get pecan, so I buy pecan off of people, they can't get alder, so we swap. Pretty cool gentlemans handshake if you ask me.
