Ah ha! Sorry Ken, I was under the impression from the beginning that you were looking for the RCBS primer strips not the strips with primers.
I just talked with Natchez Shooters Supplies as I was making another order and he said "we have plenty". So you might want to give them a call at 1-800-251-7839. The smallest order is 1000, just like it is for regular primers. Example: order number CC0084 is for 1000 CCI #300 (lrg pistol) in APS strips - $16.58.
