Extended Warranty ?
Congratulations on your new washer and dryer.
I would not get the extended warranty if they give it to you for free, Extended warranties are not only an incredibly poor buy [ you usually get 25% back of what you pay them in actual service, State lotteries pay twice that much if you really like to gamble with your hard earned money ], but even worse they take away any control you now have on who will fix your machines, and how your machines will be fixed [ used or rebuilt or new parts ], and when you might get your machines fixed.
Extended service plans generally only guarantee one thing, you will probably get POOR SERVICE when needed. It is interesting that appliance buyers that buy extended service plans usually end up replacing their appliances much sooner than consumers that do not buy these plans.
SAVE your money, if you have a serious problem in the first few years complain to the manufacturer and the store where you do business, they will usually help.
