Re: warranty plans
There are 2 flavors of contract, 'inclusive' or 'exclusive'. The 'inclusive' contracts will cover the things listed in the contract and NOTHING ELSE. These should generally be avoided. The 'exclusive' contract will cover anything EXCEPT the things listed in the contract. Make sure you review this list carefully. In either case, make sure you know exactly what you need to do to be eligible for (usually the maintenance documentation required) and receive service (the authorization procedure) since any company will deny your claim if you don't fulfill the contractural requirements completely.
Also, check out the company AND their 'reinsurer' financial condition. Many extended warrantees have become invalid by the collapse of the insuring complany.
