All the kits are free, that's why they don't show up in shop. Once you play a game and select a kit you should see them in the bottom bar :)
They will cost cubelets, vanity points, or ranks in future. But for the 7 days we want people to just have fun and wear them, and it encourages people to tweet about it and tell their friends. But thanks for the tip :P
The reason the kits are temporary because its an event, and we want to have more of these in future. We may keep the odd couple of kits and make them cost after the event is finished, I like that idea :)
We just didn't want any of the kits to cost, because with the release we knew they would be temp. We didn't want players spending points, for then a week later, all the kits are removed and their points wouldn't be refunded, which meant much rage. But I wouldn't mind keeping the odd few kits :P
