If you've ever bought a Coach purse, you know they aren't cheap. While the company's lifetime guarantee isn't the finest available, it's worth noting that, according to the Coach website, if your Coach bag requires repair or replacement, Coach will do it under the warranty for a fee of $20.00. However, as with most warranties, this one has some limitations. For example, the Coach website states that "fading from use and exposure to sunlight are both unavoidable factors that will not be covered by your warranty". The site also notes that "dirt, stains, and damage caused by misuse or abuse of the bag" are not covered by the warranty. Finally, the site advises that "if your bag is missing any part of its lining, such as the front flap or interior trim, it cannot be repaired or replaced." Still, for only 20 bucks, it's a good deal. Just make sure that you keep track of your bag's serial number so that you can file a claim if needed.
