More than 400 people have already signed up to earn money for shopping on the Post's new website Thisiscashback.co.uk.

The Post has teamed up with around 2,000 major online retailers, high street shops, brand names and service companies which have links posted on our Thisiscashback website.

Richard Coulter, assistant editor of the Post, said: "In just three days, more than 400 people have signed up to our cashback site – a sure sign that our readers can spot a great opportunity to make some extra cash.

"It's worth saying that the cashback is being paid for shopping which would have been done anyway, so it's not costing people anything.

"And with £5 to be paid each time a friend is referred, signs up and reaches the payment threshold, many people have already gone through their email address books to try to bring others into the scheme."

The site features everything from electrical items to fashion, and today we turn the spotlight on the fantastic cash which can be earned by buying broadband and mobile phones.

All you have to do to qualify for the cash back scheme is visit the retailers' websites by using the links on our website.

On joining, your account will be credited with £5 to get you started.

Then start shopping and every purchase you make will earn you cashback amounts.

As you shop, the amount in your cash back account builds and then gets paid directly into your bank account every time you reach £25.

You can also earn £5 each time you refer a friend who also reaches the £25 cash back target.

If you are looking to get connected to broadband there are plenty of deals and cashback offers on our website today.

For example, if you buy your broadband from Virgin Media you can get up to £32.50 cashback, combined with other offers on the company's introductory packages.

If you sign up to BT broadband through Thisiscashback.co.uk you can get up to £25 cashback as well as £20 off your first BT bill.

Mobile phone company O2 is offering up to £22.50 cashback on its services.

Speaking of mobile phones, if yours is due for an upgrade there are plenty of offers on Thisiscashback which will earn you tidy sums of money.

Network provider O2 is offering mobile phone customers up to £20 cashback on all its latest deals.

Tesco is offering £12.50 cashback on contract mobile phones with all major networks.

Phones 4 U is giving up to £13.25 on all types of phones and packages.

As well as earning cash back there are plenty of offers, sale prices and online discounts provided by our retailers.

We do not use any complicated points reward system. Our rewards are given back in cash to our members.

You may think there is a catch and wonder why we are able to do this.

Well, when our members use the links on our site to buy products or services, the retailers give us commission for the sale without any extra costs or charge.

We share this commission with you – unlike a lot of other internet sites and shopping directories.

Shops do not charge you more for going through our site. You pay us nothing. Ever.

There is no obligation to buy anything and you will never receive any spam or junkmail.
