This is something mostly only mustachians can relate to for sure. Posted briefly in someone's journal, but the full tale is below for your momentary diversion:
I wanted to open a CD at a new credit union for the high rate. I had $X in a savings account that had been churned for the bonus, but was waiting for the time to pass so there was no account closing fee and the bonus wouldn't get yoinked back.
The CU requires a $5 minimum balance at all times in the savings account (this is common) and I was prepared for that, so sent a paper check in the postal mail* for $5. Later, when the new account was opened and the old account could be closed, I would EFT the $X and open the CD.
Well, the check finally arrived at the CU two weeks later and they put a hold on it, as is common for new accounts. At this place, the hold time is 9 business days. Before the check arrived, and during the 9 days, I'd executed numerous transfers** from the bank the check was written on for $500 (transfer limit), adding up to waaaaay more than the check amount. And still there was a hold. On the 8th day, finally all the funds were in the new bank, but! There was still a hold on the check for $5.00. There was also a different kind of hold on another $5.00, because the minimum balance has to be met with "cleared" funds.
So my total balance was $X+5, but the available balance was $X-5. Dammed*** if I'm going to open a CD for $x,995. So I called* and they released the hold (a whole day early, lol). And lo, the CD was finally opened. There was much rejoicing. Huzzah!
*so old fashioned!
**to avoid wire transfer fee
***yeah, I'm a bit stubborn
