Generally, No. Just making the purchase with my Amex credit card gives me an extended warranty
And honestly, I've never had any electronics break during the extended warranty period, I usually don't have electronics break at all. Usually my electronics are either duds right out of the box during the return/exchange period or they last years and years and years.
The one anomaly, my Microsoft Surface Pro, died just months after the extended warranty period I was offered at the time of purchase, so that was the closest, and ultimately the warranty I was offered wouldn't have mattered anyway.
The one exception I've made is I've paid the $30 extra for AppleCare on my wireless Powerbeats Pro earbuds. Batteries don't last forever, and nobody is cutting open wireless earbuds to do a battery replacement. If the battery goes to shit in 2 years hopefully they'll just replace them with a new fresh pair.
