I have quantities of most sets and am willing to work out a discount (including shipping) for multiple sets, be they the same or different.  I usually list one or two sets of each at a time.  Let me know first what you're interested in and I can list an individual set or package to meet your needs. 

I have most Multi Ad sets from 2005-2012.  These include everything from major stars to hometown heros.  I have about half of the current MLB players in these rarer minor league team sets.
