The prepositions that most commonly follow the verb deal are with and in, depending on meaning. In fact these collocations are so common, that deal with and deal in are often treated as phrasal verbs (or sometimes, prepositional verbs), for example at the OALD (scroll down to Phrasal Verbs). But it appears that in one corner of the English-speaking world, at least, deal with has a competitor.
A commenter on the language blog Pain in the English had noticed this sentence in the New Zealand Herald:
“Perhaps it’s time to deal to the ads that are just plain downers?”
Of course, there's no logical reason why deal should be followed by with. After all, we have the very similar expression see to - If you deal with the soup, I'll see to the main course. But with is what we're used to, so anything else sounds a bit odd.
