Query: Fast shipping; atrocious packaging (leaked inside)

This was shipped and delivered quite quickly. However, the packaging was totally inadequate. A four-pound plastic bag of a toxic, powdery substance was stuffed into a USPS flat-rate mailing envelope barely big enough for it. There was no padding or any protection other than the product bag itself. In fact, the bag was leaking when I opened the package.I managed to salvage most of the powder and clean up will not be ordering any more items from this vendor.I realize the vendor probably chose this packaging to minimize the shipping cost. But it was not worth it.
