Last week, since there was a significant "sale", I purchased from my local national big box store an Apple Watch Sport. The outside box was shrink wrapped and the inside watch box was shrink wrapped. Once I opened the inside watch box, all plastic wrapping materials were on the watch band as well as the plastic wrapping material on the charger and its cable as well as the thin protective wrapping on the charging disc. Everything appeared new and in place. Then, when I tried to pair the phone it was LOCKED to another iPhone. This was a brand new, sealed outside and inside, watch. I phoned Apple support who verified that the watch I purchased from the national big box store was less than my best buy ever made. Even though I purchased the watch last week, it was in-fact first purchased in September 2015 and was locked to a phone thousands of miles away from my home...in a state I have never even visited. I called the big box guy at my local store to see if they had a different (higher priced) one in stock and if I can stop by to exchange. (I purchased the watch at another store since the version I originally wanted was out of stock at my local store.) He said no problem as long as the serial number on the receipt and watch matched the box. Shouldn't be a problem, right? WOW!!! The serial number on the receipt matched the box BUT the serial number on the watch WAS ENTIRELY DIFFERENT. Now my best buy for the day started turning sour. They said I would have to bring it back to the store where it was purchased since they NEVER heard of anything like this before. I went back to the store where I purchased it and was treated like a criminal by the first person I spoke with....really, I am an "elite" level customer, have spent quite a bit on money in the store, they have my e-mail and address and they really think I'm going to switch out a $300 item! I do have to say, that the manager of the store and a very pleasant woman, who I think was the technical support person, who I guess was kinda a "geek" made it right. They exchanged the watch. But the biggest issue here is how could a watch with a different serial number get into the box, be wrapped like new, and then be subsequently sold as new. This does not appear to be the big box store's issue buy Apples. Do they refurbish returned items and then sell them as new?!!! I believe that's against the law in my state. Any similar experiences?
