Does anyone know if the TP costumes be leaving the shop or will they be staying indefinitely? As far as I’ve seen, there is no end date posted. If they will be leaving the shop after a certain period of time, will there be any warning?
Thanks 
Unsure about if there IS an actual time limit, but there doesn’t seem to be! All the costumes were added have stayed so far, and I think they would say something if the costumes were limited time so I don’t think you need to worry 
That sort of information would certainly be included in an official announcement, if this does apply to a costume in future.
