How do you determine the order of deals in your comparison tables?

Every day we categorize thousands of deals that arrive in our networks. Using a special algorithm, we find the best performing, popular, or greatest deal that provides excellent value to our users. These "featured deals" we select based on their usefulness while considering cost.

What you pay for them is a fair price despite being a bit more expensive. However, if you review these offers, you'll find that you are actually paying less for a premium service. In fact, some of the amounts you pay go to your supported charity groups. As an added-value service for our users, we even allow you to filter these deals per cost. You can even apply filters to find the deal that best suits your lifestyle.

We want to make sure we only offer the best services to our customers. All the networks published here have excellent service records, including some reputable virtual networks.

We make sure that all our service providers are worth your money. After all, customer satisfaction is our aim.
