I use a Glade Plug-in in the apple cinnamon scent in my bedroom. Just from using the scent in one room, it makes the whole house smell like just-baked apple pie. My roommate loves it!
If you're looking for shampoos or body-wash fragrances, there's a thread about
Philosophy Body Wash/Shampoo here. After receiving great reviews about the Philosophy body washes/shampoos from the GCers, I went to Sephora to see for myself. They smell so good! I bought a bunch of the "Cookbooks" for friends that Christmas. Their scents really do smell like the real thing.
