Here's how the conversation goes...
"Hello, Mr. Gundealer. I'm looking for some of those CCI primers that cmoe in the plastic strip."
"Sorry, son, but we don't have any."
"Well, gee, Mr. Gundealer, if I order 5000, would you be kind enough to get them for me?"
"Why sure son. I can order them this afternoon, and they'll be here in three days."
"Oh golly gee, Mr. Gun Dealer, that would really be nice of you!"
"No problem, son. But I do require payment in advance on special orders."
See how simple it is?
