here you go 2 keys -> http://www.tf2wh.com/item.php?id=654;6;6e25d15e69049e7b53ae90f4f25c9497

on your links there is a 3 keys sold one, but the other 3 keys is unsold and the 3.5 is unsold as well (no surprise) current price is fine, maybe even 6.33 - 8 ref, but not what you suggest (in my opinion of course)

Im tryng to sell mine for 3 keys for a couple of days now no luck, downvoted.

I don't know why I comment on F. minigun suggestions. If you want to sell a festive minigun in less than five days I think you should ask for around the 2.5 key range. I think the christmas hype has met its limitations for now.
