What do people do with their commons and uncommons they have no need for?? I have so many:/ I wish I could trade them away..
Get a gift box!
I store them in shoe boxes, fat pack boxes, empty booster boxes. Any box really. You'd be surprised how much some commons and uncommons are worth over the yearS. They do take up a silly ammount of space but ya know I've needed random stuff and have also traded so they are worth keeping!
Another idea is if you seperate 4 of each card out from the bulk of your card pool (keeping the best quality, etc) then you can trade/sell or even give away to some new players at your LGS, to help them get started.
Then store everything else, and if you have been OCD enough to categorise or at least sort them in some way, when cards get reprinted, you might find you want to pull out your old ones and use them instead :)
