Link 1 only offer I see is for 5 ref

Link 2 Higher offers are fairly old, and their attempt to make the level seem special may have skewed the offers

Im not really convinced, but I won't downvote this just yet

bought one for 2 keys + 1.33 ref after 3 days offering, looks like some sellers expect at least 7 and 8 ref and wont accept any lower offers, also thin supply, sold out at WH, I would say 6 ref should be the new suggestion since it was imposible to find for 2 keys or lower

This is the trade from where I bought it, he asked me to add a rec http://www.tf2outpost.com/trade/5445534

I very recently got one for 2 keys flat with no hassle, I don't think this needs an update...

This is the only Vintage Tower I could find on all of Outpost with a 2 keys or lower buyout and it is a 19 hour old trade.
