ORIGINAL REPORT: Online retailer GameSeek has announced plans to temporarily drop the price of an Xbox One console with FIFA 14 to just £299.99 - £100 less than the standard retail price.
The price drop forms a part of GameSeek's 'Co-buying' promotion, an initiative similar to sites like Groupon that offers a product at an increasingly reduced price as more people pledge to buy.
On top of that, the retailer will also be reducing the price of Titanfall on Xbox One to just £30, offering a substantial saving on its normal price.
GameSeek says that each co-buy will only last for a "few hours" and that there will only be a "limited number" of each product.
