I’d been happily using Plant Fusion calcium for a couple years when it mysteriously disappeared from Amazon. Since Amazon couldn’t tell me when or if they would sell this product again, I looked up the company’s website. Sure enough, they were still making their calcium. Better news: they offered me a much larger quantity at zero cost. Wow! Thinking this kind of price reduction doesn’t happen every day, I went to their website the next day. Price for the calcium was still zero, so I ordered more bottles. My order was accepted. But the next day, Plant Fusion emailed me, claiming the zero price was some sort of system error, and canceling my order. They refunded the shipping cost I had paid, so I am not out any actual money. But jeez, I sure wish they had found and fixed the error before it disappointed me. Good product, even if I have to be a little wary when ordering.
