UPDATE: Specific trade-in prices detailed.
Update: HMV has clarified to Eurogamer that a 3DS costs £109.99 when trading in a DSi XL; £139.99 when trading in a DSi; and £154 when trading in a DS Lite.
Original story: HMV is offering an unmatched (on the high street) trade-in price of £200 for a Nintendo 3DS.
Considering you can buy a 3DS at HMV’s website for £196.99, that means yours could be a teensy profit of £3 – albeit in-store credit.
