It cost alot to ship to po boxes I normally pay $1.50 to ship to house addresses. I just shipped to po box last week an it was $7 which outrageous for shipping costs
It depends on where you ship it (how far way the address is) and how much the package weighs. If you need other information, just ask the post master, but he told me that in no way does a po bx cost more to ship to because it is just like any other united states address.
