That's a damn good deal for one of the GBA's best action shmups.
(Gamer's Gift Card is a card you buy that you put value on. For instance, you can put $20 on it and give it to someone to spend, or keep it for yourself. The main thing is, each one comes with a $5 off coupon. Some stores make you wait a day before the coupon works, but most you can just take the card right up to the front and buy the game in a 2nd transaction)
