She probably doesn't tell DWP about any earnings. She claims she's not on benefits
She has an autistic child, he would have been more comfortable with some familiar clothes from their home. I bet she's been referred for grants and charities such as women's shelters and churches etc that can help with the children's stuff.
It's really infuriating when there's some with no support, no family or friends, kids and no money. She's waving it in people's faces, just like she did with other money she got before.
