Hi. I don't know if this has been asked already but I've been wanting to trade in my 3ds AND my brother's 3ds. I've heard you get $100 In-Store credit if you trade. Can I get $200 dollar In-Store credit if I trade in both? Will Gamestop let me system transfer all my data from my current 3ds to the new one. I have an 8GB SD card in my current 3ds. Can the transfer move ALL the data/music on my current one to the 4GB Micro SD card? I also have games in there too. How long will this trade in thing last? How are you doing?
