Retail chain HMV has outlined its trade-in plans for the forthcoming Nintendo 3DS handheld, ahead of its launch later this week.
The company is offering an extra £20 discount to customers handing over a DS Lite, DSi XL or DSi in exchange if pre-ordering by March 24, bringing the ticket price down to £109.99 - while those doing so are also entitled to a £20 HMV gift card.
Meanwhile, customers exchanging those older consoles for a 3DS between March 25 and April 7 will still see an additional £10 discount on top of the trade-in price.
The retailer has also taken the unusual step of guaranteeing a trade-in price for the 3DS itself, to the tune of £200, if handed in by April 7.
"We want to help make this one of the biggest and most memorable games launches ever, so HMV's going full-out to offer 3DS customers the best deal anywhere on the high street," said the company's head of games, Tim Ellis.
HMV is Nintendo's official partner for the launch, and is opening 100 stores across the UK at midnight on Thursday, including regional flagship stores LiverpoolOne and 150 Oxford Street, London.
The first 500 customers to purchase a 3DS console at the London store will also receive a free 3DS game of their choice.
UPDATE: HMV has clarified the levels of discount that the three older DS SKUs will offer, with a 3DS priced at £154.99 plus a DS Lite, £139.99 plus a DSi and £109.99 plus a DSi XL.
