Returning Item bought on ShopParks app to WDW

I bought a shirt on the app that is too big. Does anyone know if I can return it to WDW when I'm there later this month or do I have to ship it back?

I've mailed back things that I bought on the app. They go to Memphis, but then they're sent back to the park. I only know that because I got a call from WDW last time I returned something. The phone # on the caller ID said so. She was calling from a merchandise location to confirm that I was returning the item. I say call the CS number on the app and ask before you take the item all the way to the park.

I would call and ask if you can do this. That way no unexpected problems when you arrive at DW

I have been told as long as it has the Disney Tags on it (or you have them), any place on Disney property will refund. I received an Olaf Hat for Christmas gift and it was purchased at the Disney Store in New York. I already had the hat. Disney tags were still on the 2nd hat, I took it with me when I went to Disney a few months later and actually returned it at the Animal Kingdom Lodge gift shop. Now, they gave a Disney Credit instead of money, but hey, Disney Credit is better than nothing. I believe the only reason they gave me the GC was because it had been several months.
