If you are looking to pick up some cards to finish off your set, this might work for you. Check out my Set Builders section at my eBay store.
Each listing in the Set Builders section contain a drop down list where you can choose as many cards that you need to finish off your set.
Currently, I have over a dozen drop down lists consisting of Baseball & Football cards. I will be adding more dropdown lists every few days and will also be including some non sports as well.
Follow this link to see all the Setbuilder lists available at this time:
