None of your links have sold.

Even if you did sell one for 10 keys, one trade isn't enough evidence for a price change.

These are going up so fast

i bought all the ones that were on outpost about 3 weeks ago. like every available one, for 8-9 keys.

sold them all in the past week, for 10 or 11 keys each and i only accepted pure keys. all sold out now, but this suggestion is accurate.
