Some databases are available from a number of different vendors.  What do you do when Vendor A offers to sell you a group of databases which you have already subscribed to from Vendor B?  Do you consider every new offer that comes your way?  Or, do you have a general guideline about when to consider switching vendors for same databases?

Thanks,
