Affiliate Marketing Secrets

I have a start-up and for the first time I am sending out marketing/media kits to about 80 businesses, and I’ve read that it’s lame to address them to “person in charge of purchasing” or “Buyer”. I instead should be finding out who the buyer is and addressing them personally.
The problem is that leaves me calling about 80 businesses to inquire about who their buyer is, and the problem on top of that is that I hear it’s hard to get an actual buyer’s name out of whoever answer the phone. Apparently it’s top secret information, and people like me need it, so a I’m between a rock and hard place… ANY INSIGHT?
I’d greatly appreciate EXPERIENCED input/advice. Oh, and I should mention most of the businesses I’d be dealing with are bookstores, and poker retailers (mostly online poker stores)…. I say this because the businesses I’m looking at are not large corporations with headquarters, if this influences your advice.
Thank you in advance for any and all experienced insight/advice/comments/etc.
