All of the shipping companies charge based on dimensional weight, which is the size of a package as well as the weight of it. Although pine straw is not really heavy, it is bulky. Our bales are compressed for shipping and the dimensional weight is 66 pounds. Bags of QuickStraw have a dimensional weight of 32 pounds. We receive a volume discount that we pass on to you. You will find that even with the shipping charges what they are, we can ship pine straw right to your door at prices that are very competitive with other premium mulches.
