I have not yet posted any of my brass on Gun Broker. If someone else is using my name, I assure you it is unauthorized. I can also assure you that this is a very good price, even for 1x fired 338 LM brass (Lapua brand). Partly due to the sheer volume of the brass, but more importantly, the very high quality and consistency of the brass. I will include shipping if you buy 500 pieces. The price I compared to on Midway's site is their sale price, and they are backordered at that. I will promise you that you are coming out on the plus side by saving $0.69 per piece of my brass as compared to new. Thanks for your inquiry.
