"If you really need a sad really bad I would contact whoever your chip service is and make sure they pick up a set for you. They will have to pay $5 per chip so I am gonna assume they will offer them too their customers for around $7 or $8."

If U are really doing it for the HOBBY & COLLECTOR U would be putting out more quantities of the chip. By using a chip service still does not mean everyone will get them.
NOT HAPPY IN FLORIDA. (I know my fault for not living in LAS VEGAS)
PS---By the way how much are U going to charge on your site???
