This is why you buy stuff from Nordstroms. They rock. I'm never buying anywhere else.
Excerpt from their customer service LiveChat follows:
Tim H: Hello and welcome to Nordstrom, Charlie!
Tim H: I see your question: I have 2 shirts & pants that are over a year old but are in near new condition with the minor exception of having been ruined due to laundering them with some wax lip balm. Can I exchange these?
Tim H: Were these items ordered through Nordstrom.com, or in the store?
Charlie: In a store
Tim H: Charlie, do you still have record of the purchase?
Charlie: I'm guessing no..:^(
Charlie: It is nordstrom brand stuff if that's important
Tim H: One moment and I'll look into your question.
Tim H: Charlie, you will not have any problem exchanging your items at any Nordstom store. I would suggest giving one of our Personal Shoppers a call at 1.888.282.6060. We could then try and find record of your purchase. I ask that you call due to the fact that this forum is not secure and for your protection, I can't ask for specific personal information.
