I haven't noticed this before but today I checked IVPN and saw that they offer discounts for businesses and non-profit organizations. If someone here is from nonprofit, you can get IVPN Pro for $3 a month and if you are from a company that needs a VPN, IVPN offers Pro plan for $5-$9, depends on the number of members.

I'll also soon recheck the prices of listed VPN providers and also update this thread with Black Friday deals. I think that Mullvad and IVPN won't offer discounts but many Non-Privacy Focused Mainstream VPNs will offer good Black Friday deals.
Stay tuned for a news update.
