#1.)  Products already last a long time.  If your product doesn't break during the original warranty period, chances are it will last beyond the extended warranty period too.  Especially if you're not buying off-brand stuff.

#2.)  Service plans are WAY too expensive.  Most of them cost about the same as what you'd pay for one repair:  Up to a third of the full cost of the product itself.  Just save the money . . . and pay for repairs when you actually need them.

#3.)  They rip you off in the fine print.  Some plans start on the purchase date, which means they're covering the same period as the manufacturer warranty.  Other times a company will give you a flimsy excuse and refuse to honor the contract.

--For instance, they could "determine" that the damage was YOUR fault.  Or they could just say there's no authorized repair provider in your area.

#4.)  Good companies will want to help you anyway.  Companies want to keep their customers happy.  Even after your warranty runs out, you might still get free repairs.

#5.)  You might be covered by a credit card.  Lots of credit cards offer benefits that extend a manufacturer's warranty for a year.  So you might not need the service plan even if something DOES break.

#6.)  State laws may already extend your warranty rights.  Most states have laws requiring products to be free of major defects for a reasonable amount of time.  So a court could force a company to fix something even after the warranty runs out.

#7.)  It might be an easy fix anyway.  If something breaks, a few minutes on Google might show you how to repair it on your own.

#8.)  You can probably get renter's insurance cheaper.  If you have homeowner's or renter's insurance, add whatever you buy to it.  They might give better coverage for less money . . . and they don't run out.
