Was told 5 business days when I applied (on Monday). Just got an email with from "Chase Fraud Alert" (Subject: Your new Chase card is on its way!) with a UPS tracking number. Supposed to be delivered today. Very much an under promise over deliver thing going on.
I wonder who the genius is at Chase who decided to use "Chase Fraud Alert" as the sender name to send cards out. This will definitely make me pay less attention to emails from this sender name in the future.
