Sale 2)

blip:

Bulk deal for pure, sold along with an Orbiting Fire PJs and a Miami Nights PJs. Agreed price for Aces High was 100 keys.

Seller: https://backpack.tf/profiles/76561198141496043#!/compare/1707436800/1707523200

One key missing from the compare.

Buyer: https://backpack.tf/profiles/76561198045296162#!/compare/1707004800/1707523200

Doesn't show all 500 keys due to some of them being bought on the same day.

Miami Nights PJs was briefly removed from my inventory so it could be signed (we forgot to do it beforehand lol), with the Spectral Swirl Pool Party and Scorching Bicorne used as collateral. It was quickly returned to me as shown in this compare link.

100

Considering the previous sale, I would go for a 95-100 range, but there are now generic Buy Orders for Unusual Cat's PJs offering more than 95...
