Return policy sucks

I have ordered multiple items from this company and most have been decent. A particular item, of which I have ordered 4, stops working after a few weeks. This is the recharchable bar light. As with most bad reviews here, my complaint is that one cannot return a thing without cost to yourself. Most online companies will happily pay the courier cost to return the item as it is them at fault. However, I suppose that if you sell a lot of faulty things, this becomes inviable. Why would I pay R75 plus another R75 plus possibly another R75 (if I want a replacement) for something that cost me R59 to start? It's *******.
