SAFC fans have until the end of the week to win a piece of club memorabilia.
A football shirt, signed by some of the 1973 FA Cup winning team, is being raffled by Argos in the city.
It is part of the efforts by North East branches of the chain to raise awareness of dementia, and money for people living with the condition.
In a bid to raise nearly £2,000, Argos staff are cycling 1,600 miles on static bikes in stores – the length from the Stadium of Light, Sunderland, to Stadium of Light in Lisbon, Portugal.
Sunderland store manager Stephen Snowball has been helping to raise awareness of dementia by handing out thousands of leaflets to Wearside customers, revealing five things everyone should know about the condition.
Customers were also asked to round up their purchases to the nearest pound, in order to raise vital funds for Alzheimer’s Society. Stephen said: “It’s fantastic that we can combine our love of football with raising vital funds for people living with dementia.
“My colleagues have had great fun and the customers really showed their support.
“We also hope that our partnership with Alzheimer’s Society will help raise awareness of dementia, and the support on offer to help people living with the condition stay in their own home for longer.”
