It's very easy to buy and sell for 2 keys. There's no need for an extra one refined.

But nothing is wrong with this suggestion: Easy to buy at 5 and easy to sell at 6. The price should be adjusted then, if these trades are being done. Upvote.

actually I just got one of these in a trade and it wasn't easy to move. Mine had a craft number and people avoid that. If it didn't I could have gotten 2 keys, but I don't see people paying more than that.

I had two TCs in the last two days, sold them both for ~5 Ref in items after a day or two of offers. I didn't get any 5 Ref/2 Keys offer.

I managed to sell mine for 2 keys within 24 hours. I had a friend sell his for 2 keys as well... but it took a week before anyone noticed it.

this hat's just overrated.

could not sell in 5 days for 5.33 ref

Could not find a single person selling for 5 ref. Many b/o at 2 keys / 5.33 -- current price is fine, proposed price range is too wide.

You lucked out at 6 ref, most sell for 2 keys or less. I've seen several being sold for 4.33 ref over the past few weeks. And you've said that your buyer was looking for just that level, that in and of itself negates the change as he is willing to pay more for a particular level.

This is an unnecessary move.
