Just got off the phone with customer service for the Costco American Express card.
While I would have thought that the extended warranty support would have continued to be valid even after the card itself was terminated/ converted, the customer service representative spoke to her team leader and confirmed that in fact this was not the case.
Specifically, I was told that when the Costco Amex card is no more later this year, I will lose all of my extended warranty support.
I was advised to use my Blue Cash Amex on purchases if I wished to ensure my warranty was extended.
Perhaps something all of you SD'ers already knew and planned ahead for, but must admit this is one that caught me by surprise. I have been continuing to use my Costco Amex since I have had good experience with them backing me with warranty issues before, but now I will only be used at Costco and for nothing else.
Mods - if this is in the incorrect area, please move. I have seen several topics related to credit cards posted here and while this quite the opposite of a hot deal, figured best to let others know so they can plan accordingly if they have not already.
