While I appreciate the anxiety on whether the refund gets loaded onto the pre-paid card or not, can I suggest assume 'the worst case' for the time being.
The issue isn't whether you get the rebate, it's HOW you get the rebate.
So assume it'll be by0 check, and if it turns out it's direct deposit, you'll be delighted.....
from the various new reports I've seen, direct deposit is targeted for mid-April with checks 2-3 weeks behind that. Obviously, they can process a lot more direct deposits per day than checks.
