I've done a few breaks simply because it's cheaper than buying full boxes and you don't have all the base laying around that no one wants. Sometimes I have come out on top and most times I have lost money. Granted, I don't post the cards on eBay I just add them to my org and hope someone wants to trade for them. If I sold them I could probably recoup some of the lost money.
