Le Creuset Support Says Warranty Only Applies To Purchases From Their Website

This just can’t be right…right? I purchased enamel cookware from Nordstrom that has developed weird chipping along the lid rim. Regular use, no abuse. Customer service just replied to my warranty claim by saying the warranty only applies to products purchased from their official website. I find that hard to believe. Can anyone back me up?

UPDATE: They said that since the damage doesn’t affect the cooking surface, I’ll need to pay for shipping and they’ll offer a “one time replacement as a courtesy.”
