I haven't yet seen what camp equipment is available for this 2021 Postcard Week.......that information doesn't seem to be available on Wiki yet... I've been regularly checking 👀🤓🧐👁️
EDIT: Postcards Week 2021 just became available in my game now. 📬
Sounds like you are becoming passionately frustrated with the camp equipment situation as well.
I really don't know what to do with my Event Special Items from both St Patricks Day 2021 & Alice In Wonderland.
I've kept my Event Special Items from Valentine Day 2021 & Christmas 2020 so far to spend next year.
Would be great to know if we were going to have St Patricks Day events every year with a new story & then the previous year re-released for free....just like Christmas, Valentines Day, Easter, Diggys Birthday & Halloween.
So then we would know to either spend the Event Special Items or stockpile them until the following year for the free re-releases.
