I just heard from an SP-internal-source that this is true, not just a rumor. If/when I have additional details on this story, I will post a further update. This news is shocking.
UPDATE #2, SATURDAY, 8:00 AM:
Check out the "comment" that was just posted by someone apparently in the know! (Comments appear at the very end of the blog post.)
This morning, I heard from three different, usually very reliable sources, that Service Point has shut-down (or is in the process of shutting down) its U.S. operations.
