ALFA-X and Clear Nankai rapi:t were not in Expo. Believe it or not, ALFA-X was very find to find, even the Plarail Shop wouldn't sell it. So the only place to find it was "Joshin", and I took the last one at a discounted price at 3696 yen over the 4200 yen retail. rapi:t is found in the Plarail Shop but not in Expo, that's weird...
Edit: Found limited quantities of ALFA-X at retail price in Hankyu Departmental Store and in Daimaru Shinsaibashi. Daimaru Umeda did not have stocks.
