Hello, I'm currently staying in Da Nang, I want to look for this Vietnam exclusive special Casio Calculator model (fx-880BTG) does anyone know where these calculators can be found? I tried finding several results and contacting stationery and bookstores in Da Nang. I even tried emailing Danang Bookstore but they didn't reply and I'm going back home in 4 days from now. If anyone can help thank you.
