Check before you buy
Checks to run before you buy from an unfamiliar shop, register a domain, buy a printable, pack a power bank for a flight or book a cheap fare.
Each guide covers a cost or rule that is easy to miss at checkout.
Check an unfamiliar online store with seven free tools. Compare a domain's renewal price with its first-year price before you pay. Check a printable's file format, licence and printing needs. For travel, read a power bank's watt-hours against the airline rules, and include baggage when you compare fares in Google Flights.
Before paying for Proton VPN Plus, check whether Proton VPN Free covers your task and compare the first payment and renewal cost over the periods they cover.
