NordVPN is one of the cheapest VPN service among the top rated competitors. A 2 year deal costs $3.71 on the official website which is 68% discount, but you can use 90% promo code to get the best NordVPN price. Unfortunately starting of October 2020 the company doesn't provide a 3 year deal anymore. The price can be even more attractive during special holidays such as Black Friday, Cyber Monday, Back to School, Halloween and so on. NordVPN regulary runs exclusive deals and provide coupon codes throughout the year. The combination of good discount coupons and seasonal deals can help you save upto 90% of the regular price. To apply NordVPN coupon just choose your subscription plan, scroll down and under "Got Coupon?" insert your promo code. I noticed that different discount codes can be combined so try to use several of them to get the best price. At the present time the company provides NordVPN deal with 90% off exclusive coupon.
Another good side is a wide range of payment methods. Besides credit cards you can choose QIWI, Webmoney, Amazon Pay, Crypto Currencies, Alipay and Union Pay. Unfortunately NordVPN has stopped supporting payments via PayPal explaining it with "inability to run full control over the purchase". I don't think this is a serious drawback, but it can push potential buyers towards a competing VPN.
