Glad it worked out for a few out there but there is a lot of people including me who got unfairly burned on this trade-in fiasco. Here are some examples.
And those threads on this same forum:
I traded in my Note 4 for the S9 plus. Today I found that they declined the rebate because there were damaged. It said they found water damage. I was disgusted to find it since I had having so many issues with Costco about this trade-in. Finally when I thought I cleared all of then, they said it was damaged.
