Giveaway for Kirin Hyoketsu 4 packs from liquorland. Limited to 20,000. Haven't received the confirmation yet but it does say up to 2 days.
Must be trying to compete with Suntory 196 dominance here.
EDITS: Have now received the confirmation, took about 12 mins to come through.
Also, I haven't redeemed yet but users are commenting that getting the attendant to type in the barcode instead of scanning is fixing redemption issues.
How about instore?
