I also grab any new Yankee Candle items I see for cheap to have on hand for last minute gifts. We have the flagship store here so Yankee Candle can be found semi-frequently at thrifts.
I've seen a few, almost not burned at all, but the scents just weren't my cup of tea. I have a few favorites, which I use during the holidays (I love "Home Sweet Home" and "Buttercream" scents; I also like one of their pine scents, but I'm not sure if it's "Christmas Wreath" or what).
