Sold with Aces Brigade + 4 keys for Blizzardy Yellow(49)

notihng on the Brigade

Total sales @:

14, 21, 29 keys

buyers up to ~16 keys,

Xerogyf's Part:

https://marketplace.tf/items/tf2/111;5;u57

$59.99 / $1.69 = 35.50 keys

mp.tf sale from a hidden history, currently outdated but was at the time this suggestion was created (all other sales are also outdated now, but that shouldn't matter)

Bridage has a sale now as well:

https://marketplace.tf/items/tf2/105;5;u59

$29.99 / $2.03 = 14.77 keys

Seems kind of high (already a mp seller under that sale price) but its all we have to go off of.

That makes sale 6: 49 - 15 - 4 = 30 keys. Worth noting that the belt has buy orders higher than bp price now, but the sugg there was accepted right around when the sale occured so 49 should be fine to take there.

That gives sales at:

14?

21

29

30

36

I would call 21 and lower low go 29 - 36 keys here. The RA Elfin sale also supports a higher price.

Cashew's Part:

elfin has buyers at 29 so that sale is at least 33. The buyer at 21 also resold for 29 the next day so excluding 21 seems reasonable.
