Jamestown Distributors specializes in marine products. I don’t really have a need for marine stuff, but I always find them useful when I need specialized stainless hardware, screws, nuts, bolts and epoxy type finishes. Stuff that the local Ace doesn’t carry and you’d never see it at HD. Not cheap, but not terribly expensive either.

Expensive. But I was able to get some precut stainless stock that was frustrating to find locally. Again, I wouldn’t buy stuff I could easily get locally, but at some point you just need it and chances are they can get it to you.

Woodworker’s Source is my favorite. These guys wrap up hardwood and ship it to you for less than my local Los Angeles suppliers can even dream about. Their Project Packs are the bargain and I buils a Bubinga vanity from one that the chicks swoon over.

I just did my kitchen (and I did my last kitchen in my last place) using these guys. Great product at an unbelievable price (at least for LA).
