No, American Express matches only the manufacturer's warranty, up to one year (Standard) or up to three years (Centurion). In this example you would have:
1st year - Manufacturer
2&3 year - Contract
4th year - American Express
I'm confused. I thought they *match* the manufacturer's warranty, which means if the manufacturer's is only 1 year, it will only be 1 year. If the manufacturer's is 3 years, it will be 3 years.
