Yes, I'm aware of 5/24 and I have two spots open, both of which I want to fill with Chase cards - Freedom and CSP, as a matter of fact. Then, I'm in the garden for quite some time.
The March 15th date is somewhere on my page on the website and, I believe, it was also in the email sent to me, asking if I was "still interested in CSP". I can't find it now, because I only have my Android with me. I don't really worry about the date, anyway. If, in June or August, I have higher scores and lower CU, I'm sure the offers will stand.
Also, my thanks to GrasshopperStudent, since my Laguna Beach Chase branch is next door to my work, I'm not going to make a move without sauntering over and speaking to a Personal Banker.
