My last order took 10 days back in December. I ordered an item during the woot-off last Thursday and as of today i still haven't received a shipping email. Very slow.
My experiences have varied. On a single-item Woot!, of a DVD±RW drive, I recieved the email a day or two later, and had the drive within 5. On a previous woot-off It had taken upwards of a week.
