Query: poor shipping from this vendor

The verdict is still out on this product. I am currently taking a host of other vitamins, so I am not sure what is working at this point. My problem is with the vendor. I received this product and a large percentage of them burst. Given the price, I may only have a 20day supply. Given the cost of this product, this is not a great deal. I'm purchasing elsewhere for my next bottle...
