You certainly can! Most commercial VPNs will allow you to pay for a single-month subscription - but it's important to remember that you may end up paying double (or even triple) the amount for the VPN in the long run. This is because VPNs offer their biggest discounts on their more long-term plans, and it's why we recommend opting for one if you're looking for real value for money. Alternatively, check out our VPN free trial guide to see how you can put services to the test without risking your cash.
