Plusnet has extended its current offer on Unlimited Broadband and Calls, and added £25 cashback to the deal.
Consumers signing up for the broadband package over the internet can pay just £2.99 per month for internet services and home phone calls for the first year.
This enables them to save £84 during the first year of an 18-month contract - £109 with the new cashback offer factored into the equation.
Plusnet describes the package as being "perfect" for large families, downloaders and gamers, since there is no monthly data allowance.
As well as unlimited usage, subscribers can take advantage of up to 16Mb download speeds, supported by a free four-port wireless 'N' router.
Customers can also take advantage of a free activation - allowing them to save another £25 - Plusnet Protect powered by McAfee, 24/7 customer support and the free help tool Plusnet Assist.
Plusnet Unlimited Broadband and Calls includes Plusnet Weekends - covering calls to UK landlines, 0845 and 0870 numbers.
Calls to Plusnet Phone customers and Plusnet Support are also free at all times.
Unlimited Broadband and Calls subscribers also have the option of upgrading from the Plusnet Weekends phone tariff to Plusnet Anytime or Plusnet Anytime International 300.
For an extra £5 per month, Plusnet Anytime offers inclusive calls to UK landlines throughout the week, plus 25 per cent off calls to popular international destinations.
Plusnet Anytime International 300 costs an extra £7 per month on top of the £2.99 customers initially pay for their broadband package.
This add-on includes 24/7 landline calls, and 300 Anytime international minutes.
Consumers have until Friday October 18th 2013 to take advantage of the discount broadband deal.
