Price Range

There are a bunch of unusual offers at 1.8 - 2.1 buds, Both of the sellers on outpost said they would take the 2 bud pure offer, but neither of them was able to. Shy Ronnie (first link) said he would take the Peace Spartan + 16 keys, or around 1.9 - 2.1 buds in mixed unusual / pure.

1.8 buds for the lower bound because people are offering up to 2.1 in unusuals, and 2 for the upper bound because that seems to be the price that the sellers and one buyer in particular was willing to trade for.
