My first was a failed attempt at getting the $5 PH titles from bb.com
But I used the 10% code they sent as a consolation to get an Xbox bundle for $180 (they were $180 retail at the time for the base system) that included Fuzion Frenzy, Star Wars/Sega GT bundle, and GTA double pack. (on sale for $200 less 10% = $180) I didn't care about Fuzion Frenzy, but the GTA double pack along with Madden '04 were my two main reasons for getting a system, so I was very happy. And turns out I've played the crap out of Fuzion Frenzy.
I also picked up an extra controller S for 10% off ($27) Today I would have simply used a GGC to get it for $25 outside of the web deal, but I didn't know any better at the time.
