Consequences when confidential business pricing information is disclosed to the general public?

When confidential pricing information that is intended for one organization and its members is disclosed to the general public, are there consequences to (1) the organization or (2) the discloser? My nonprofit organization was given very favorable pricing on an expensive product--for example, 70% off iPads, by the manufacturer. The organization was given specific details about how to obtain the discount, involving calling the manufacturer, giving a password and ordering the product. The favorable pricing was intended just for my organization's members, and it wasn't to be shared. One leader of the organization emailed the information out to its members. There were unfortunately some glitches with the email. Long story short, the discount details and steps to obtain the discount were posted on a widely-known Internet site. What's our liability? What's the discloser's liability- if we can track the discloser down, and if the discloser rightfully (or not) had the info?
