Back in January, British rocker Ozzy Osbourne revealed to the world that he had been diagnosed with Parkinson’s Disease – PRKN 2 – an issue he has been dealing with since 2003.

After making music for the past 50 years, Ozzy and his band Black Sabbath have retired from touring and have some old merchandise left over. They have posted those items on their eBay page for fans to bids on.

April is Parkinson’s Awareness month so Ozzy and the band will be donating 10% of sales from those items to the The Michael J Fox Foundation for Parkinson’s Research.
