Vouchercodes.co.uk is currently offering a voucher that will give you 5 per cent off a MacBook or iMac at Comet.

It is well known that discounted Apple products tend to be rare, so if any of you are in the market for one of these machines then it might be worth taking a look.

The current price of the MacBook is £867, which will give you a discount of £43, and the iMac is even better as it's showing up on the Comet site as £975 (less than the £1,020 that Apple is asking on its site) which gives a discount of nearly £50.

The catch is that the offer ends Thursday 27 January, so you'll have to get your skates on. The offer works in the usual fashion, just go to the Vouchercodes.co.uk site to pick up the code and then follow the link to Comet; you can then add the code at checkout.
