6 buds in mixed (burning old guad + sf flamethrower) - rejected

6 buds in mostly pure (5 pure + sf flamethrower + crate 40) - rejected

5.9 buds in unusuals (scorching fruit shoot) - rejected

5.65 buds in unusuals (scorching marauder) - rejected

5.9 pure / 6 unusuals - so I'll set high end as 5.9. Low end is tricky. Per the trader himself, he's not concerned with profit so much as getting a nice hat. Says "both slouches over 5," so I suspect if he got a hat he really liked valued at 5, he might take. So I'm posting that at the low end.

If anyone has bought or sold one in the last 2 weeks, please let me know what it was traded for. It may help with the low end. The 5.9 pure used as the high end was made within the last 2 weeks, so I think that's a legit high end.
