New customers signing up before March 31 will be eligible for the freebie.
PlusNet is starting a major push to get online gamers signed up to its Broadband Your Way Pro service.
Broadband Your Way Pro is specifically designed for online gaming, with all gaming and VoIP traffic identified and prioritised giving low ping and latency and a reliable and stable connection.
This can be yours for £19.99 a month and comes with 10GB of prioritised usage. Bandwidth between midnight and 8am is also unmonitored meaning late night gaming won't eat away at your allowance.
Until March 31, 2008, new customers signing up to PlusNet's Broadband Your Way Pro service will also be eligible for a free £40 voucher to spend at any GAME store in the UK.
You can find full terms of the offer and more information on Broadband Your Way Pro over on the PlusNet website.
