As title says, go to the link and click on the option which says pay what you want. It will lockout the first two items of the bundle but will keep the third one active which is subscription for one year. I put $1 and went though Paypal payment. Got code in my account within 10 minutes which had to be redeemed on anonvpn.io
I don't know how effective this will be for VPN anonymity but from looking at the reviews online, slightly better speeds than PIA.
Their website is very shiny but doesn't seem to have much info so I am going to try it with openvpn client and do the dns check etc before using it. Should be good enough if you just want to use it to trick websites into believing that you are in the USA or UK although they claim no logs policy.
There is a referral link but its not approved so I wont post it.
It's not pay what you want. The minimum is $1.
