I don't exactly remember by brain fart, but at some point, it said "or deposit your funds via your online banking account". I was busy at the time and figured it would save me a trip to the bank. Then I vaguely remember thinking "Where do I put my reference #" before clicking submit. After that, I knew I was going to have some problems getting the deposit credited. I did not think I was going to have my communications to recover the deposit put off however.
I figure they need to wait a LONG TIME to have your check clear 100%. Otherwise people could deposit bad checks (fake checks, NSF checks, stop payment checks etc), and get bitcoins for them.
