This is the "real world" version of the web scam that sends you an email "confirming your order" and stating that your account (usually PayPal) will be billed (usually about $500) when your new computer is shipped. If you click their link for more information it connects you to what looks like the normal PayPal site but of course is their own (frequently relocated) malware distribution site.

You of course are asked to enter your PayPal account information and other personal (financial) data so that they can locate the information on "your transaction." In some cases, various links at the phony site may be busy downloading their keystroke loggers and backdoor openers for continued future use.

Examples of this particular one have described it as "very professionally designed;" but of course it makes no difference how nicely done the scam is - a scam is still a scam.
