The Stardust was a casino in Quebec, Canada that closed. StraightPokerSupplies picked up most of their inventory, and put them on eBay. NobleCountyDanny bought them all...heck of a deal. He then resold a bunch of them last year (link)
, and again a few weeks ago on the other site.
At this point, you will have to look out for a sale either on eBay or in the Classifieds. SPS still has some cash $5 here
