I've got the following modules, all in mint condition. Price is $5 a pop, you pay shipping of whatever sort you prefer (no surcharge, you pay what I pay). Payment via Paypal only; PM me, or email at zomben@yahoo.com to make an offer.
A1, A2, A3 (please note, these are the C&C "A" series. Nothing to do with the old AD&D "A" series)
DB1, DB2
U1, U2, U3
GG1, GG2 (these are the Goodman Games licensed C&C modules)
Descriptions of these can be found here: http://www.trolllord.com/newsite/cnc/index.html
