This morning a “Special offer” button showed up in Proton Mail for me offering a 1 year Proton Family plan for 33% off. That comes out to $239.88 (USD) per year. https://proton.me/mail/black-friday
Just heads up for linux (and those not aware I guess)
ProtonVPN app itself (on windows) has the same banner deal as well, but it links to a deal that is unlimited for individual (Not family!). So deal isnt exclusive to family edition only.
Not sure why its not displayed on their web apps. Or maybe im blind and I missed it, :P
