I received a BIG help in my Gypsy Queen set building yesterday from Ryan at This Card is Cool. A few weeks ago he received about 900 cards from this year's GQ and was trading off all of the duplicates. I put together what I could for him and he was very generous in what he sent my way. The cards finished off probably 2/3 of what I needed for my base set and he also sent an SP that I didn't have.
He also sent me a couple of Topps inserts, including the Stan Musial that finished off the Lost Cards set for me.
Thanks for the trade Ryan!
