NordVPN shows "Save 69%" on a 2-year plan, with the renewal price in small print
Step by step
- 1Default effect / status quo bias
The page opens on "2-year plans".
- 2Reference price
The Basic plan shows "Save 69%" and "$3.49 per month", plus "+ 3 EXTRA months".
- 3Price & attribute framing
Small print: "$312.93 $94.23 for the first 27 months… Savings: intro vs. renewal prices. Renews at $139.08/year."
Prices quoted in dollars ($), exactly as shown on the page we captured (US-priced). Prices vary by region and change over time.
The psychology
Why it nudges
"Save 69%" is measured against a struck-through reference price: the small print says the saving compares the intro price with the renewal price. A low monthly figure on a 27-month plan frames a large upfront bill as small, and "3 EXTRA months" adds a bonus. Whether this lifts sales for NordVPN is not public.

Context
A consumer VPN sold mainly on long multi-year plans paid upfront.
Honest nudge or dark pattern?
Grey area
Grey area: the saving is measured against the renewal price, and the upfront total and renewal price are in much smaller print than "$3.49" and "Save 69%". It sits close to the hidden-costs line. See deceptive.design/hidden-costs.
Steal this, honestly
- If you show a saving, show what it's against at the same size.
- Show the upfront total as clearly as the monthly figure.
What to test: Monthly-equivalent vs upfront-total headline price. Measure purchases and refund requests.
Next: run it on your product
