I think it's been a while since these prices due to inflation etc.
Not sure if there is a limit but seems to be for me on a per order basis.
Ultimate(amazon.com.au) - $20 ($18 S&S) SOLD OUT
Active(amazon.com.au) - $18 ($16.20 S&S)
Sensitive(amazon.com.au) - $18 ($16.20 S&S)
Can anyone please comment on if the ultimate is worth the extra dollars? Ta
