Who doesn't love a sale, eh?
I'm selling any regular boosters from before M12 that I have left over for $2 a piece. I'm just trying to move inventory out the door, thus the low price.
I'm not exactly sure of what all I have, though, so it's up to the mercy of whatever leftover stock I have on hand to what you'll get. It doesn't go back past Zendikar, though, and doesn't include any Worldwake, I can safely say that much.
M12 will still be the regular $2.75. But at the prices some Rares are going for, that may not be such a bad deal. ;)
