Selling for 1 bud

Analysis:

All the links are pretty helpful. The newer ones still get offers 25-key offers in less than a day, while links 2 & 5 has a lot of great offers at 36 keys due to how long they've been up. There's even one up in classifieds for 1 bud, but it looks like he could get a little more if he's patient.
