Seems to have been moved to bot?

Then this bot was subjected to the Gladiator exploit

New sales and information:

11 keys

7 key seller

Overall information:

3 sales @ 9 keys

New sale at 11 keys

Young 1 month seller at 7 keys

https://mannco.store/item/440-prismatic-haze-unusual-taunt-luxury-lounge

Mods can't check and the sales are not usable but:

https://gyazo.com/a94a68231c0ad3f70819cf4603dba38b

3 sales at $24.99 in the past 3 months on Mannco, which is ~13.6/7 keys rounding up to 14 keys

With the young seller at 7 keys, I don't see a suggestion going through at the current price.

If the 7 key seller was to sell then, I can see 7 - 11 keys working here, ignoring all the mannco sales.

Just my 2 cents, wait for a mod to read through this all.

Edit:

Also for sale 1, I guess you can use that sale to price the taunt over there since no new sales have happened on that taunt and there are more sales here.
