BT has added to the appeal of its home phone and broadband bundles by doubling the value of the shopping vouchers on offer to new customers.
Previously, consumers signing up for ADSL broadband deals - such as BT Unlimited Broadband - were entitled to a free £25 Sainsbury's gift card when they registered, but this has now increased to £50.
And new BT subscribers taking out an Infinity fibre broadband deal - such as BT Infinity 1 - now receive a £100 gift card, up from £50.
BT ADSL and fibre broadband customers can also take advantage of a special introductory discount at present.
The broadband provider is offering 50 per cent off the cost of internet services and landline calls for the first six months of an 18-month contract.
BT Unlimited Broadband - which now comes with a £50 Sainsbury's gift card - offers up to 16Mb download speeds, with no restriction on data downloads.
Weekend calls to UK landlines are included, as is a Home Hub 4 wireless router.
The package also offers unlimited BT Wi-Fi minutes, BT SmartTalk, BT Parental Controls, 2GB BT Cloud and free access to the BT Sport app and online player.
With the half-price offer taken into account, customers can pay just £8 per month plus line rental for the first six months of their deal, rising to £16 per month plus line rental thereafter.
For households seeking faster broadband speeds, BT Infinity 1 offers downloads of up to 38Mb and uploads of up to 2Mb with a 20GB monthly usage allowance.
Subscribers also receive inclusive weekend calls, a BT Home Hub 5, BT Wi-Fi minutes, BT SmartTalk, BT Parental Controls, 2GB BT Cloud and free access to the BT Sport app and online player.
The fibre broadband package is priced at £7.50 per month plus line rental for the first six months, rising to £15 plus line rental for the remainder of an 18-month contract.
