i don't know if this was mentioned anywhere else but i did get a butterbeer mug at the park when i went on the 8th of August. I also saw that pygmy puffs were in stock. The line to get into Dervish and Banges seemed like it took longer to get into than FJ (which was about 30 min for me with a posting time of 45). i got a ravenclaw shirt, hogwarts hoodie, two ravenclaw keychains (one spins in the middle the other says Ravenclaw quidditch), 3 hogwarts crest keychains, a slytherin crest keychain, a ravenclaw pin, a ravenclaw tie lanyard, a chocolate frog( hufflepuff
), a sugar quill. a box of bertie botts, ravenclaw quidditch magnet, and a box of pink coconut ice. The pink coconut ice tastes awful and leaves an oily filmy feeling in your mouth XP. I wanted a ravenclaw hat but unfortunately they are sold out. I even tried the universal store, the trading company, and the universal studios store on city walk. They still have the other three houses however.
