Yes I own one, but the listing here is a bit old and I think I've got plenty of evidence. There are pure offers at the low and high end of the new range, and unusual offers lining up with it.

The evidence from the previous price adjustment supports this higher range as well. One sold for a max plus a bud, and 2 others added sweets for 3 buds
