Phil and Andre talk about some things you may not need and could be wasting your money on.
Extended warranties on most products are a waste of money. First check what is included with the standard warranty and if your credit card offers a warranty. They do make sense for some less durable goods.
Travel insurance is often worth the small cost, especially if you are going somewhere remote.
Car warranties should also be looked at with suspicion, sometimes you are essentially just prepaying for expensive repairs.
Mortgage insurance may not be as good as it sounds.
