Ruby Slippers (Adam and Eve)

Does anyone know if the Ruby Slipper by Adam and Eve has been discontinued? I noticed it is very hard to find. It is a pretty red glass dildo with a glycerine fluid on the inside that you can put in the freezer to make it cold, or put it in hot water to make it hot.
I have, however, seen it on ebay and was thinking of buying it (new of course!)
I am just wondering if anyone reading this has tried it or seen it in stores.
Thanks! less
