PIA VPN has an ongoing deal that slashes a whopping 83% off the regular monthly price and adds four more months for free if you purchase its three-year plan. Under the deal, you only have to pay $1.98, instead of the usual $11.95, per month, which comes to a reasonable total of $79 for 40 months. If you're not familiar with the VPN service, PIA (short for Private Internet Access) prides itself on being an "everyday" easy-to-use VPN, but arguably the best part about is it allows an unlimited number of devices to connect to the service, and that it has servers in about 91 countries (including all 50 states in the US). 

Like most VPN deals, you have about a month to decide whether you want to pay for the service you've just tried. If you don't, you can request a refund with their 30-day money-back guarantee.
