Considering that it costs $6 or about 3-4 keys to finish a tour, I don't see why it would go under 3 keys.

I believe 6 ref would be more accurate. The bulk of the sellers wants 2 keys + 1 ref. Sure, there's desperate ones that sell for 2 keys, but it's not the majority yet.

I'm gonna agree it was super easy to buy this and all the other bot killers at 2keys each and that was a few days ago.
