Sundown Magnesium 500mg

I really do like this product a lot and only use it to maintain good bowel movements. I would caution using this as a form of magnesium supplement, because the oxide version does not get absorbed well by the body, and its a cheap end material. Now brings me to my three stars review. Its mainly for the quality and the price. The product was solid for many years, when it was only $5.99, and recently not only has the product price shoot all the way to $15.99? The bottle lid is also faulty and doesnt close well. I just want to know why does the seller raise the product to 16 bucks when they are selling a cheap end form of magnesium? And I hope new buyers are aware that they have been raising the price like crazy. But the product itself has been going down in terms of quality. Its really sad that the company decides to screw over the royal customers by raising price and decreasing quality once anything gets popular.
