I usually try random codes with the following format: COMPANYNAME15, COMPANYNAME20, etc. Every once in a while (maybe 10% of the time?) I get lucky.

WELCOME10, WELCOME20, etc also work a good amount of the time. A lot of the sign up for our mailing list and get a discount promo codes match up to WELCOME plus the percentage off.
