Unlike Upper Deck MLS cards, it's pretty hard to finish the TOPPS MLS sets. I need a fair number of cards from the 2013, 2014 and 2014 Chrome sets, not so many from the 2015, 2016 and 2017 sets. Do you have singles from these sets to trade? I'm also looking for inserts from both the UD and TOPPS sets, and am willing to trade my inserts 1:1. Please e-mail me if you are interested: martinbtatuch@yahoo.com.
