How do you combine shipping, when shipping is included in the price?

Nothing against Burt personally, but people can choose who they wish to deal with and sell to. Heck there may be someone who doesn't want to sell me chips because of something I wrote here. It's their choice.

I buy from Chuck as a NIS for $1 Nevada chips. He's prompt, fair and always been a gentleman in our dealings. I suppose there are other NIS around, but that's the one I started with years ago.

Burt you might try one of the other fine New Issue Services who would be interested in selling you chips.
