Five Costs You Should Always Avoid

Automatically renewed memberships and subscriptions: Many people sign up for memberships and subscriptions that automatically renew each month with the best intentions. In reality, they don't end up using them and they continue to be charged.

Review all your memberships and subscriptions and ask yourself if you're using them. If you aren't, it's time to cancel them.

Untapped discounts or negotiation opportunities: While haggling isn't as common in the U.S. as it is in other countries, there are certain situations in which negotiating a price is not only acceptable, it's expected. Buying a car is a good example. Still, some people would rather pay the listed price instead of making a lower offer.

People often qualify for discounts because they're members of clubs like trade organizations or AAA. But they might be too embarrassed to ask about them at the register. If you're one of these people, find a less shy friend to help you.
