None of those are in the range you're suggesting. The only one "in" it is the Goggles, but the goggles REALLY REALLY need an update, they're prices almost TWICE as much a burning goggles, and twice that of sunbeams / scorching. All the other offers are in the 5-6.5 range

Downvote from me.

There's someone going around offernig 9 pure on the ghosts goggles so that's solid value holding up the high end. Did a glance around, misty skull's also holding up about 7ish, and the offer was quickly followed up with an offer to add roughly a buds worth in extras on top of it.

Other offers, a little older, are ghosts Bubble Pipe- roughly 7-8ish- and Steaming Hazmat + 1 bud + old festive weapon set- about 6.5-7ish total.

All in all, the low range seems fairly well supported, with offers reaching 7 worth without too much trouble. The high range might be just a touch high, but it's supported by a solid trade, and a recent one at that.
