Sorry i can't help with the site. I either got my fibre optic DS9 at Kay Be Toy Liqudators or a discount store called Big Lots for about $10 about 2 or 3 years ago.
I live in Chattanooga, Tennessee [USA]. But I have found these Dollar Tree stores and similar stores all over the east coast . I know for a fact they are in Tennessee and Georgia but there are stores that sell similar mechandise eveywhere but under different names. Some of the stores names are as follows:
1] Everything's A Dollar [large chain]
2] Abraca Dollar [as in "Abra Cadabra"]
3] Dollar Tree [large chain]
4] There are other independent stores with various names which are own locally. they seem to get most of ther merch from the same place.
