went to the pop-up event across town and there wasn't much tbh. it was also early in the day so most people were either in school or at work.
i wasn't sure where the event was being held inside the store so i decided to go to the music section on the 2nd level. but on the way to the escalators, i heard music that was somewhat familiar and eneded up following that towards the cafe until i saw yellow and green decorations.
merch wise, there were only the different lemonade album versions and a set of richman albums (burst version). but they did have an ot4 poster (WDA), foam lemon stress ball things, and customized plastic cups as freebies and there wasn't a limit on amount of freebies per person (just don't be a hoarder lol). i did enter the raffle but idk if i'll be lucky enough to win the signed postcard 😅
i didn't wanna seem rude by just showing up and grabbing a bunch of freebies before leaving so i ended up buying 1 album (and signing up for a free membership). normally, i'd wait until i got home to unbox the album but this was a special event + i was curious which cards were in the album so i went back to the event area/cafe and opened the album in store. ended up pulling a purple giselle and a ningning. i don't collect photocards anymore (and haven't checked templates yet) so idk which is the B&N exclusive lol
Edit: the cafe also has special drinks for the event! and according to one of the comments, the plastic cups change color with cold water.
