If you see any of mine you want on COMC, send me an offer and I'll accept the minimum offer for any of these cards you need. Use the filter box on the left side to keep looking through cards offered by me. There are plenty of other sellers on this site that can help you complete your sets as well. Send them some offers too. And they ship to Canada. Create an account if you don't have one already.

It looks like I have some of the Civil War News and Topps Wings that you need. Send me a message here if you want to negotiate further.
