Try this fast and secure VPN for under $1

TL;DR: A seven-day trial of PureVPN is available for $0.99 as of May 7, and you can cancel at anytime during that week. (Just look for the pop-up for this promotion.)

The best VPN deals can generally only be accessed if you're willing to commit to a long contract, which isn't for everyone. It's especially daunting if you're completely new to VPNs.

Most services do offer a money-back guarantee, which provides a certain level of protection. It's not the same as a genuine trial though, because these provide full access to all the features without any sort of commitment.
