You could add some proof..

Can we just make commenting on price changes mandatory? No proof will never get accepted

Bought one 1 hour ago for 2.66. Downvoted.

Of course he has one in his backpack...

*Sing to "The Lion Sleeps Tonight"*

In the backpack, the TF backpack, the rep train rides tonight...

Oh in the backpack, the TF backpack, the proof is not in sight...

We need the proof, provide the proof, we need the proof, provide the proof (etc.)

Seriously, I am getting tired of these no comment price suggestions.

I will cut your throat with this misc.

First suggestion, I'll be nice. You need to provide proof of trades that show these going for 1 key. Otherwise people will think you are only trying to increase the value of your item, which is why you received responses like you have.
