The promotion, which runs from October to December, offers free £5 vouchers and 20% discounts off products to readers of Future's technology and entertainment magazines.
Participating magazines include T3, Total Film, SFX, PC Zone, PSW and the Official Nintendo Magazine.
Cocktail Marketing, which devised the campaign, said Future Publishing would be promoting the money-off deal with full page ads in its magazine titles and mailings to subscribers.
In addition, BoysStuff.co.uk will flag the deal on its website and send out customer emails.
Gary Beresford, managing director of BoysStuff.co.uk, said: "This is a fantastic way for BoysStuff.co.uk to raise brand awareness among a key target audience of affluent opinion-forming males, while also driving sales by offering a unique offer to these customers."
