I was on the lookout for Rockwell Razor 6S and found an Adelaidian business, Ministry of Shave, that sells it. Lucky enough that their Father's Day 15% coupon still worked for me today, which brought it down to $118. Free shipping applies to transactions over $75.
If you don't mind paying $5 for postage, the Rockwell Razor 6C is not a bad option.

The main differences between 6S and 6C are to do with material and weight. For details, feel free to check out the comparative review:

In Australia, the only other vendor that sells it probably is Beard and Blade ($149) and they are out of stock.

Beard and Blade sells 6C too but more expensive ($84)

I believe, outside Australia, retailers sell 6S at about USD$100 (AUD$138)

N.B. Because I am not affiliated with MoS, I honestly have no idea when the Father's Day promotion ends.
"Free shipping applies to transactions under $75."
Shouldn't it be OVER $75?
But great find, I have the 6C already and it's an awesome razor.
