It doesn't matter how fast stuff arrives when it's packaged terribly and damaged. I've received more damaged merchandise from Amazon than every other online retailer I've ever ordered from combined.
That's about where I am on this too. I got the $25 Chibi Robo GC and that's enough for me. The $15 one in addition would literally mean they were giving me the game for free + $10 in credit. A $5 game is good enough for me.
Holy crap. My K-Mart never has any of the good clearances but they had these prices. Picked up the last copies of New Super Mario Bros U, New Super Luigi U, Pikmin 3, Donkey Kong Tropical Freeze, and Zelda Wind Waker for $143.
Simply amazing prices and the cashier was a totally nice gamer.
