How much does it cost you per month for a 70% off for 2 year package? I have seen Express VPN cost you around 6.67$ a month if you buy their yearly plan and Mullvad VPN is still cheaper even if you buy it for a month. However i heard that Mullvad VPN support is not as good as other giants in the market like Express VPN etc.
It is even cheaper to rent a simple VPS and deploy your own VPN service on it. The simplest VPS costs about $2-3 per month, and for personal use, it is more than enough. Moreover, a personal VPN is much better than any public VPN service because the IP address is used only by you and not tens/hundreds of other users. This makes sense because, for example, some gambling sites may restrict access to the site or its functionality because of this.
