I had an AXA code on my rez, now have CZF and it saved me about $11 a night, just over $100 for 9 nights. Of course, then I went and added a night, and changed the last two nites to AKL! So they wound up getting more money out of me! I'm probably making my DU agent crazy with all these changes! She's always gotten the codes applied before I even found out about them!
