Normally sells for $90.
I would say price match at JB Hifi and OW instead of buying from Amazon so that more people can make use of this deal - leaving Amazon as a reference point for price match. The previous post of Z3000 carbon filter got sold out pretty soon after posting.

Wow that is cheap! The Samsung I bought is almost 8 times this price!
