How this comparison is made
Prices come straight from the stores' own feeds, in USD for United States, and are cached for about 30 minutes; hours-to-beat and the pros and cons are our editorial estimates. Cost per hour is the cheapest current price divided by hours-to-beat. No ads, no affiliate links and no paid placement — a store link earns us nothing. Every weight and threshold we use is published.
