Agreed. This scam originated long before the internet existed. Businesses have long been warned to watch out for fake invoices. They're usually for office supplies and <$500, but the scam is very old. A common variation on the them is where they actually ship some low value item, wait just long enough for UCC return rights to expire and then send a ridiculous invoice. If ignored, a threatening follow-up comes that includes the proof of delivery of the item and late penalty threats. The item was usually shipped signature-required, so the proof more intimidating. (If you're wondering, the law is generally still on your side but you shouldn't just ignore the letters and keep the item even though they will likely give up anyway.)
