Bath amp Body Works - Wallflowers
At bath & body works they currently have a 2 for 20$ deal on wallflowers, which are little plug-in things that are filled with oil in a variety of amazing scents. They fill up the entire house but not too strongly, just a hint of the scent, they are definitely a must have. I bought Sandalwood Vanilla for upstairs and Leaves for downstairs. Sandalwood Vanilla has sort of an earthy vanilla-y scent to it that is just amazing and Leaves makes your house smell like Christmas which is why I love it so much. You should definitely check them out!
