I just bought 1000 rounds of Starline 10mm brass from Double tap sport (member dealer) for $180 shipped to my door. When I looked around in Winnipeg for brass the best I found was at Wholesale Sports. It was $31 for 100 pieces, so 1000 would cost be $310.00. All things considered that deal from Double Tap Sports was almost half price shipped.
I was happy with the purchase. Even the price on Starlines website direct from the States was not any better. (Not that you could order from them anyway!)
Hope this helps.
