Raise $800 via Social Media

I’m a pensioner who urgently needs an animal-protection suit so I can walk and exercise safely in public. The suit costs A$800, an amount that is out of reach on my fixed income, so I want to run a small-scale online fundraiser that speaks honestly about my situation and asks for help...
