I'm visually impaired so I ask a colleague to assist with purchases of onlibe goods. Last year bought comforter set only started using it this year. Upon using it I realised it forms unbearable ***** on inside of comforter. Left the product at woolworths centurion mall because they said product is now worth 1 cent should have returned it 6 months ago. I'm not surprised it's reduced from close to R2000 to 1c
