It says on the shop page that she'll be here for a 'limited time', but how long will that be? Sorry if this has already been asked. Thaaanks. :)

The shop's open year round, it's just that you can only get and give flowers in order to get the necessary coins during the event.

i didn't think esther's shop remained open year round.

Oh, okay, thanks everybody. <3

Yep, just bought stuff from there with leftover coins about 6 weeks ago. So it's open after the event.
