This is Cara Duggan. She's from Belfast, Northern Ireland, and earlier this week she tried to buy a used Nutribullet on Gumtree.
Duggan's mother, Kim, was diagnosed with stage 4 oesophageal cancer last year and a Nutribullet is the best way get high-density nutrition into her, but they cost around £130 ($200).
Duggan said the family was trying to fundraise to start covering some of the costs for her mother's treatment.
"A while after her last chemo session Mum's legs started swelling which turned out to be blood clots, but as they were undiagnosed they had travelled to her lungs. Apparently, this is a really common side effect of chemo. These blood clots have left her with no energy and she's been really struggling with nausea, so we decided to get her a juicer," Duggan told BuzzFeed News. "We were already fundraising to cover costs of therapies and supplements for the cancer, so we couldn't really afford a new one, hence why we reached out about the second-hand one."
