Since I've been bussy with work, didn't have the time to research, so I'm reusing my last suggestion before I forget.

Sale 1 - 07/21/23

I bought a Time Warp Virtual Reality Headset, traded a Green Confetti Pencil Pusher + The Holiday Headcase + a Strange Festive Wrangler with Exorcism.

Since the Green Confetti Pencil Pusher it's outdated by 3 years (last accepted price submission) and my trade was more than 4 months ago, decided to not consider it for the suggestion, just wanted to be transparent sharing what I paid for mine.

Sale 2 - 09/23/23

The current owner paid 100 Keys pure + Strange Australium Scattergun + Strange Australium Rocket Launcher

New price suggestion

The sales are from different item ID.

I'm only taking Sale 2, because it's been more than 3 months since Sale 1. Considering the Aussie Scattergun as 44 Keys (quick buy listings for non killstreak/spelled ones) and the Aussie Rocket Launcher as 47-49 Keys from it's recent approved suggestion.

The low value would be 100 + 44 (Aussie Scattergun) + 47 (Aussie Rocket Launcher) = 191 keys

The high value would be 100 + 44 (Aussie Scattergun) + 49 (Aussie Rocket Launcher) = 193 keys

That would be an average price of 192 keys, let me know what you think.
