The sweet gal at the checkout counter there gave me the Smart Card discount too so total discount was 28%. I have no idea what the "window" piece was supposed to be. But it has enough hand-painted garden-y looking stuff on it and cute kitty in the window that I thought $3 was an okay price. I'll put it under the carport or somewhere else if I decide to seal it.
It swivels and this is what the back looks like. It has a hole at the top and had a dowel perch to look like a giant birdhouse or something ... but it obviously isn't. Just decorative shelf, I guess? Not sure of the purpose of the swivel base. Still, I couldn't make it myself for $3.
