I can sell mine at 15 keys, does that means price should be reduced to 15 keys?

I feel like these will drop below a buds shortly, once the initial demand goes down

Yes, they'll probably drop, but not now having only around 50-70 of them.

E: I've been doing a bit of a research today, MANY have Unusual offers worth +1.5 buds or key offers or other offers. This guy didn't had too much luck selling it so instead, he IS trying to reduce the price. Don't lower it today, have the patience to sell something... mann.

sold mine at very first for a lantern baker and i add 2 buds.now its dropping like a stone.

These should go down in price, since more and more people are playing MvM and more and more of these will drop in the future.
