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.
To be eligible you'll need to trade your 3DS in by 7th April. Essentially, then, you can own a 3DS for around two-weeks for no money at all. That's the hook, anyway.
HMV also offers a £20 bonus on DS Lite, DSi and DS XL trade-ins if you pre-order a 3DS by 24th March, taking the 3DS price down to £109.99. A £20 HMV voucher is thrown in for free.
If you miss that pre-order window, you can still receive a bonus £10 by trading an old DS model and buying a 3DS between 25th March and 7th April.
It's a big push by shop-chain HMV, the official launch partner of Nintendo 3DS. The HMV on Oxford Street, London, will be the centre-point of the shop-chain's Nintendo 3DS midnight launch extravaganza this Thursday.
A grand total of 1200 shops will open at midnight on Thursday to sell the Nintendo 3DS. HMV stores will account for 100 of those.
