Potentially stupid question but, if I were to trade in my 3DS toward an XL version, would I get an extra 10% as a PUR member?
FYI: Having just done the trade myself, try to build in an extra day to your 3DS trade-in if you want to actually transfer your data. The Gamestop I went to didn't have wifi so I had to do a return and rebuy.
Tues: Bought 3DS XL, Transferred data
Wed: "Returned" 3DS XL, Rebought with trade-in of 3DS
Considering you're running out of time on the $100 trade-in, take that time into account. It took me a good hour to transfer everything (ambassador games, mainly)
