This needs to drop in price. Not much activity in people buying.

A few sellers between 6.5 and 7 keys:

Most people sell at 7.5 or above, but they have very little activity. Most are 1 day old or older.

There are also a lot of people who want 8-12 keys for it, but I didn't include it because it isn't in the current range.

Did I leave something out?
