Hey i was waiting for 3 days and i want to buy osu! t-shirt (isshoni pippi) and it keeps telling it's out of stock. Do you guys know when will they start to sell?
Follow @ppy on twitter for restock alerts and information.
Store is a second priority, so there is no set date on any restocks.
Hopefully sometime after Twitchcon things should change and pick up in the store section of things, but until it does happen, you'll just have to hang tight and keep an eye open.
