I will be buying my kitchen appliances soon. I'm almost decided on Kitchenaid so it seems that the amex plat would be the best extended warranty as it would extend the 5-year warranty by a year. CSR would only extend warranty 1 year past 3 years. Is my thinking correct? Also, I've never put that amount on my Amex - the check spending power says good news, that amount is approved - is this enough to avoid a rejection at the store? I have an Amex offer for 2k points when you spend $4000 up to 3x so that will be a nice bonus. Thanks so much.
