When making a price suggestion, you need to use compare links to show the sale. Linking the users' profiles isn't enough. Here is an example of valid evidence:

Item 1: https://backpack.tf/item/12776779699

Sale 1:

https://backpack.tf/profiles/76561198062747535#!/compare/1769385600/1769472000

https://backpack.tf/profiles/76561198304790008#!/compare/1769385600/1769472000

Neither of the comapres show the 34 keys so it would be good if you provided a screenshot of the sale

Some other in-date sales happened too:

Item 2: https://backpack.tf/item/5924744574

Marketplace.tf to Scrap.tf, doesn't appear to have actually sold on MPTF so must have been withdrawn and dumped

Item 3: https://backpack.tf/item/11779635029

Dumped to STN for 29 keys 43.11 ref (~30 keys)

Sale 4:

https://backpack.tf/profiles/76561199564942025#!/compare/1770076800/1770163200

https://backpack.tf/profiles/76561198307473975#!/compare/1769990400/1770595200

25 keys match, was most likely higher

Sale 5:

https://backpack.tf/profiles/76561198307473975#!/compare/1773619200/1773705600

https://backpack.tf/profiles/76561199581722058#!/compare/1773619200/1773705600

Dumped in bulk to STN, 24.33 ref matches

Should be fine to exclude 30 given that buyers are currently at ~32 keys
