There are many edge cases on dimensions other than product. I live on a small island that enjoys US Postal Service by boat. Amazon will ship to me. The high number of mom-and-pops that aren't set up to ship to me creates a situation where, if I need something Amazon doesn't have, I usually have to send it to someone in the US and once enough stuff builds up, they ship a package to me. This holds true even for international shippers (e.g. an Etsy seller in Europe is more likely to ship to the US than to me).
