I have picked up dice on eBay, from casinos that I have played at, but neglected to get a pair of dice while I was there. Usually, I get them for $2-3, same as in the gift shops, but add $1-2 s/h. Some dice were harder to get and I had to pay more. But there are a lot of dice starting $4-5, mostly Hard Rock and the Palms, in blue and green, and I have seen some over $10 from closed casinos.
