Not very likely.

While it might be possible, the minimum order of 1000 is rather large and selling them (well, tracking / packing / waiting, etc) is time consuming (compared to my day job). I also noticed that the original vendor no longer has the eight balls listed on their site, but I have the original link and they could probably do it if asked.

I do not have any more left for sale at this point, but I am sure there are a few spares floating around out there if you absolutely need one or two.
