It's not a bad idea to pair that with lawsuits related to such warranties.
Costco and Samsung are big enough that you can achieve reasonable signal.
When your local car dealer offers you a full drivetrain warranty though (assuming it's a full warranty and not one of the other ways people are often fleeced), will they honor it when the lemon they sold you breaks the first time? the 2nd? the 3rd? Will they, instead, note that most people buying that car don't have much money (or, if you used any form of dealer financing, know for a fact you don't have much money) and require you to retain a lawyer and sue them to recover any damages?
Not sure if your car example was meant to be general or specific, but Lemon Laws are extremely common across the states and are very easy to take advantage of without needing to retain a lawyer. For example, in Texas you fill out a form, pay a $35 filing fee, then bring your evidence to mediation.
