Sellers at 3, one being there for 2 months, and another at 3.61 for 4 months

https://marketplace.tf/items/tf2/1182;5;u3010 Sellers at ~3 keys

https://steamcommunity.com/market/listings/440/Unusual%20Taunt%3A%20Yeti%20Punch?filter=Mega+Strike Seller currently equals to 2.63 keys but keys have recently had a spike in price (2.07€ instead of 1.98-2.02€)

Sales at 2.95, 3.1, 3.1, 3.15, 4, 4

4 seems high, most common trading point seems to be 2.95-3.15. Even though some of the sellers have been there a long time I still think 3.15 should be included to include more trading points, but in any case a drop is needed.

Taking 2.95-3.15 keys here
