We're all being told to reduce, reuse and recycle, so when a leaflet pops on your mat asking for old clothes, many of us would be happy to donate a bag or two.
Legitimate clothes collections are beginning suffer
Some are from legitimate, long established charities.
But an increasing number are actually from commercial companies, which will take your old clothes and them sell them on at a profit, in Eastern Europe or the developing world.
If you read the small print, they're careful not to claim to be a charity - but many of those who get the leaflets feel they've been misled.
But Trading Standards officers are getting an increasing number of complaints about their tactics - and now they've organised their own leaflet drops to warn householders to be careful.

Who's collecting your donations?
Many well-known national charities organise door-to-door collections, to raise money for their work.
But if you've had a leaflet from an appeal you don't recognise, you can check whether it's legitimate.
You can ring the Charity Commission: 0845 300
Look out for this logo
In Scotland, you'll need to ring the Office of the Scottish Charity Regulator: 01382 220446
You can also look for the Association of Charity Shops' official logo, or visit their website
And you can check whether the collection is being organised by a Community Interest Company, or CIC.They're usually small organisations which use the profits they make towards local good causes.
