CHARITY workers are warning residents in Northumberland to check the small print of doorstep collection bags.
The British Heart Foundation (BHF) says as little as a third of items donated to good causes via letterbox bags can end up in charity shops.
And up to 70 per cent of the bags received by the average householder are from commercial companies who work with charities for financial gain by selling the donated items overseas. In some cases, just five per cent is paid to the charity involved in the deal.
It advises people to check any charity bags and leaflets that drop through their doors for details about the distribution of funds.
The research has been released as the BHF embarks on a Big Donation stock appeal for its shops.
