BT is offering prepaid Reward cards worth £75 with some of its fibre broadband packages.
A BT prepaid Reward card simply needs to be activated before being spent at any retailer that shows a MasterCard logo.
BT states that since the card uses Chip and PIN, it is a more secure alternative to spending physical cash.
Among the deals offering this as a freebie is the BT Infinity Fibre Unlimited Broadband & Calls package.
This offers speeds of up to 52Mbps and unlimited downloads, as well as weekend calls, 100GB of cloud storage and BT Virus Protect on two devices.
The 12-month contract costs £27.99 per month, along with a £59.99 set-up fee. This means that subscribers will get a saving on their broadband worth £144 throughout the duration of their contract.
Another package offering a £75 prepaid Reward card is the BT Infinity Fibre 2 Unlimited Broadband & Calls deal.
This offers broadband speeds of up to 76Mbps and unlimited downloads for a cost of £44.99 per month, plus a £9.99 set-up fee.
As a result, they will save £60 on broadband throughout the year. Subscribers will also benefit from 500GB of cloud storage and BT Virus Protect on 15 devices.
Both these packages include the BT Smart Hub, which BT bills as offering the UK's "most powerful wi-fi signal".
