Should you preorder?
Preorder prices are set by shops guessing demand, and Union Arena boxes have moved both ways after release: some sell for well above their launch price a year later, others for less. If you want specific Gurren Lagann cards, waiting for singles is almost always cheaper. If you're buying to hold sealed, you're betting the set ends up above its presale price, which nobody can know before the chase cards are revealed.
