Is it right for distributors to ask for bank info ...???

I'm in the process of setting up an online store. Over the past few months, I've contacted numerous distributors, and several have come back with requesting bank info on their dealer application. I mean they are asking for account numbers! Is this right? I can understand them wanting to contact the bank to ensure that I'm a legit biz. But do they need my account info? Should I just tell them no thanks, I'll find another distributor?
The problem is that certain distributors have exclusive rights from a mfg in my area, and if I don't buy from them, then ..... sol, I don't have access to that product.
I'm starting to get a bit annoyed at some of the attitudes and egos of these distributors. A lot of the policies that they send to you to sign, are almost like threats that if you don't do this, don't do that, then we will .... I thought I was the customer?
Also, any other advise on dealing with the "big tuff guy" distributor?

Getting a bit disgruntled!
