Know-How Exchange : Research/Metrics

After recently serving as Marketing Director for a major card issuer in the UK and serving a two year non-complete period I have lost track of what account acquisition costs by marketing channel are in today's card marketing environment. Can anybody give specific CTAs for the following products and channels, or your best guess: Direct Mail, Internet Banner, Internet Affiliates, Internet Search, Media, Event, and Outbound Telemarketing for Rewards, Non-Rewards, and Affinity ? Thank you for responding and I promise to any any question regarding cards you may have.
