Calbee Pro Yakyu Chips are still tough to find. The grocery store closest to my office doesn't have them yet, though I noticed they put the soccer cards on clearance sale. But I ran into the supermarket near my house, and found that they have put out their stock. I grabbed 15 bags for later; these 11 packs below were bought last week!
After 31 packs, I have 40 different cards from the 84-card base set, 4 of 16 subset cards, and 7 of 24 Starcards - plus the one gold signature Starcard parallel. That's 52 unique cards - I've had a total of 10 duplicates as well.
