I've never had much luck with the online auctions...in fact, most of the time I see I would be overpaying if I went through with an auction. But I found a great source when I was living in St. Louis and they happen to be a big volume dealer, so they get great rates. Being in the military, I was moved around a bit, but they would even mail me my order after the check cleared and it only cost an extra $7. Check out https://www.scoins.com/ for some of the best deals I've seen around.
