Added 19 keys (1 bud) for a Phosphorous Charmer's Chapeau (outdated, see extra suggestion: http://backpack.tf/vote/id/53623b9a4cd7b8c1038b4602 ) 6.6 buds - 1 bud = 5.6 buds (is overpay necessary?)

Added 2 keys and a Strange Phlog (7 ref at the time) for a Blizzardy Gibus making it 8.2 (7.4 w/ overpay)

That makes it a sale at 5.6 and a sale at 7.4! If there's anything I should change/add please let me know, or if you have additional proof :3
