Chase's own credit cards trigger an automatic refund when there's a negative balance for a month or two, and by default it's sent as an electronic bank transfer. From what I remember, this should count as a DD. p4 recently opened Chase's checking+saving $900 offer. Figured I'd give it a try and update with a DP later.
Note: Once you get the email about the balance refund, make sure to click accept as soon as possible. Last time I saw it and thought I'd deal with it later, then forgot, and after a day it expired and I had to wait for a check.


Whether this approach works hinges on how long the electronic transfer takes to land. If it drags on for a week or two, the window for hitting the card's spending requirement gets tight, so it's best to work out the deadline before you start.
