Home owning can get expensive, especially when you have fun and exciting things you want to do, but limited funds.
Habitat for Humanity, has a ReStore which you can donate and buy used items, I think that would be a great place to drop off my mirrored closet doors... those things are hideous....
Betterhomes and Garbage has some awesome reclaimed items, I saw myself drooling over some of their millwork, and I think the hubby and I might be getting a few things from there some day!
Bauer Brothers have a resale store too, with some very cool items.
UofMN has a reuse program too, with items for resale. check out their FB page for pictures
MN materials exchange has some interesting items. not a lot, but it might have something unique
and if those resources run out, there are always many other options to be researched at a later time.
