Sorry, but no. If you were to delete the DSi channel that you bought, then you would simply get no points; the only thing you would be able to do, however, is download that software again, for free. Hope that answers it.
No you cant only eBay can
i do my fc is 0647 1047 8231 do you have any Nintendo points if so i will trade
You can't trade JUST you DSi system in for a 3DS system anywhere.
no you cant dsi is to new
Yes you can OR you can trade your Nintendo DS, $100 and 2 unwanted games for a Nintendo DSi.
it cost about 99.99
no, because they're not equal in value. You may have to trade in the old Nintendo and bring enough money to make the money + trade in points equal to the price of a dsi. In other words, if you want to, bring sum more cash with you.
If you mean simply trading one system for the other, then no, you cannot. The Nintendo DSi is worth about $150 while the DS Lite is worth about $110. You can, however, trade in the Nintendo DS Lite and cash for the Nintendo DSi. If you choose that method, you will need about $40 or so more to cover the cost. You can also choose to trade in your Nintendo DS Lite plus a game or two for the Nintendo DSi.
Nintendo 3DS costs $249.00.
GameStop
Go to Nintendo DSi Shop. There will be games where you have to trade in DSi Points for the game and there are some that are free. Just click on the free game and click download.
