Unsold at 16 keys for 18 hours? And you want to increase to 18 keys?

When providing proof for a price change (price suggestion), you want to collect evidence that points towards confirmed sales.

You can do this by, for instance, pressing the ''History'' button on an item, go to a persons backpack thats in the list of the history of said item, and click ''Compare'' (right above the BP charts). Check on the history WHEN the item was traded away, then select the left and right timestamps to be specified to that day. If you did everything correct, you would see that said item was either obtained or sold for an X amount of pure (or items, which requires further calculation). But, pure defines a sale. If an item is sold for 16 keys, then you can use that as evidence. But popular items like australiums require more than one sale. Many more. When YOU make a price suggestion, YOU need to provide evidence. Not us, we are simply reviewing your suggestion.

I suggest you to close this suggestion, read the rules CAREFULLY and word for word and also check other price suggestions on (in this case) australium weapons. Observe how people make suggestion, what they do, and if you've done all this, try again.

There are still a few sellers going for under 18 keys. You should go for what Mr. Sam said and provide evidence aswell as closing this current suggestion.
