B&T Duplicate checking

It sounds like a real struggle to get B&T to understand that their duplicate checking system is not working. We are still in the trial period before we make major changes in direction (like a new vendor). I can't understand that no other library is having this trouble. My thinking going in was that B&T was large enough that we didn't have to be the leader in pushing them to improve. That we coudl be a small fish in the big pond of book vendors. Perhaps we are hitting trouble because we are not big enough to have a department that operates like the big system ones they are used to. Its like the commercial where the 2 business men (ie big firms) laugh at the mini-business man (ie small business or us) and then put an ashtray on top of the mini-dude.
