The B2B, B2C and A2B markets

Despite their occasional slip-ups, the writers on the publication I work for are capable of great wit and subtlety. Take this sentence from a recent feature:

Sometimes it's easy to forget that vans are in the A2B market

This left me briefly baffled. I knew what B2B was (business to business), and I knew what B2C was (business to consumer). But A2B?

And then it dawned on me – vans are in the A2B market because they, er, take things from A to B. Very nice.
