Mac App Deals are currently offering Flux 3 for $41 (goes up a dollar a day) with a complimentary upgrade to version 4.
Flux 4 has just been released and The Escapers are currently charging £89.99 for the full version and £44.99 for an upgrade from version 3. So this is a cheap way to get the latest version…
I have been a Freeway user since version 3 and have posted on these forums many times before. Flux has come up for discussion quite a few times before in the Off Topic forum and some FW users have started using it.
As this was such a good offer I thought it would be a good idea to share it. And I have been completely transparent about the link being a referral.
