Sources for Woodworking

The most common sources of wood are places like the Home Depot and Lowes.  However, the quality of the wood from these vendors is often mediocre or worse, the prices are not always the best available, and while they tend to have home-improvement project-style products (e.g. framing lumber and plywood), they don't have a large selection of hardwoods.

Here is a list of other vendors.  Please feel free to add to this list.

Highland Hardwoods

407 Route 125
Brentwood, NH 03833
603-679-1230
https://www.highlandhardwoods.com/
Monday through Friday 8am-4pm 

Probably the best option in NH for hardwood supply.  They carry a large variety of soft and hardwoods including exotics.  They usually have several available pieces with live edges as well as boards and planks for a variety of needs.  For hobbyists, the best prices are usually found in the shorts section (i.e. cut-off pieces from larger boards).  They usually have a good and consistent supply of more common woods in the shorts area (e.g. maple, cherry, walnut, red and white oak, etc...) and a less consistent supply of exotic shorts.  Prices in most cases are by board-foot and different milling options are available (for explanation of terms like board-foot, S4S, etc. see this page).

They also carry flooring and decking products as well as tools (mostly Festool) and supplies of things like wax and oil.

Hardwood isn't cheap, but their prices are reasonable and they're not too far of a drive for most members.

Rockler

290 South Braodway St., Ste 3A
Salem, NH 03079
603-898-5941
Rockler - Salem
Monday – Friday: 9 AM – 7 PM, Saturday: 9 AM – 6 PM, Sunday: 11 AM – 4 PM 

Rockler is more of a supplier of tools and woodworking hardware (e.g. hinges, clasps, door pulls, etc...), but they do have a fairly good selection of hardwood for hobbyists.  The prices are not all that great, however, but the quality tends to be pretty good.  They also offer classes.
