Got an offer of 2.3 within seconds of setting up my trade, within 3 days I had an offer of 3 buds, which I took eventually. Had been collecting unusual offers of about 2-2.5.

Only other one on the market (the only one on it right now, as I have sold mine)-

http://www.tf2outpost.com/trade/10290068 got similar offers, abiet less.

Both had an offer of a scorching beret from Dj Mole, possibility that the other hearts beret will be sold for it if Dj mole offers the him the same.

One of the last one got offers from the other owner of 2.5 buds, the owner said they were in no dire need of buds and had a price tag of 3 pure.

In conclusion; owners seem to wait until they can sell it for up to 3 buds, which doesn't seem to take long, it only took me 5 days, and it took another owner around that amount of time too.
