Interesting. Good to know since I have a few more certs expiring in August and beyond. Will probably just use this one for SMT since I could get it for about $25 which is less than the $30 eShop credit I would eventually have to buy for Dual Destinies (since I already have FE:A and imagine that Phoenix Wright will be at least $30 when it comes out). Probably will just preorder South Park with the $20 cert that expires in August on that though and just return it if the game reviews poorly. Wish they would give a date for that game! Or just reup this promo! Or if Amazon would upgrade my order!
Thanks again for all of the info and help, Donut.
