In an animated web video posted here, a pair of mail trucks cruise down a suburban street. The first truck, representing Google, gives way to a mail carrier armed with x-ray vision (or maybe Google Glass?) peers into an envelop, scans a keyword off the enclosed letter and uses the keyword to select a pair of coupons, which are slipped in with the letter.

On the other side of the street, the mailman carrying for Outlook, delivers a letter unopened, and proceeds to polish the mailbox.

It's not subtle, but then, what about Valentine's Day is?
