You know, some places (countries) don't allow returns. For instance, when I purchased my 22K dark pink WOC, the Japan Duty Free boutique told me beforehand no returns. And asked me to examine the bag closely before making purchase.I actually tried returning it the next day and the boutique in Paris that I bought it from (it was located in a larger mall) didn't allow returns ):
I got it tax free and will not be making a trip to Japan so I carefully looked over the bag and handed over my CC. I'm happy with my purchase.
But in your case, please call because situations might be different. I don't know.
