I have an extra DSi code that will give you 160 coins + 1000 DSi points to spend in the online DSi store (if registered before october), in exchange I want a mix-match of Wii or DS games I do not have and matches the DSi coins value (150 is okay).
Please note, that when you register a DSi, it needs to go online and link with your account to get the coins and points, so if you do use this code, you will need to give me a user name and password (I suggest you change your password in till you receive the coins and points).
No, I am not a scammer =)
I still have a Pokemon Pearl code up for trades, as well as Animal Crossing for the DS.
