I opened another account at IB and mailed a cashier's check to them. Mailman picked it up saturday from my mailbox. I was hoping it would post to the account by now... I was lazy and didn't want to make a trip to the post office (to add tracking number etc.) - just stuck a 39c stamp on the envelope and mailed it - getting a little antsy - kinda large cashier's check. Any experience how long this might take? The mail should have been delivered to IB on tuesday. I am near Chicago and the mail is going to NJ. Thanks!
