2nd sale for Rack:

Stormy Rack + Blizzardy Storm Blighted Beak for Burning Flames Master's Yellow Belt, it's fairly bulky so probably not best used here (outdated and very old mini for Beak gives 1070 - 494 = 576, generally supporting the above sale)

Stormy Rack seems to have sold for 420 keys here

Credits Blaze:

may be best to take the rack at 420 keys since there doesn't appear to be anymore valid sales.

the 560 sale is going to be high considering there is now a seller at 500 keys in classies:

there's also a seller on mannco at $999.99 (500 keys):

https://mannco.store/item/440-stormy-storm-unusual-exquisite-rack (there's also a sale there at $500 which is obviously low but supports the 420 price tag)

the person who sold it for 420 also had it listed at 460 when it sold: https://gladiator.tf/time-machine?item=Stormy+Storm+Exquisite+Rack&at=2023-02-23T19%3A37%3A00.000Z
