I was able to get one of 8 left over cow tags a few weeks ago that appeared on the weekly list...after having been unsuccessful for a couple weeks before that. I didn't even bother waiting for the tag to show up on the leftover list because I noticed before that different tags would show up at different times, not all at once. I already had my hunt code entered on the check out screen and kept refreshing the preview list on a different screen. Once I saw the preview list had been moved to the leftover list, I started trying to purchase my tag. After a couple minutes of continuous purchase attempts, it finally went through. I never checked or waited for it to show on leftover list. Like people above have said, if you're waiting for it to pop up on the list, you're already way behind everyone else. Strange way of doing things for sure.
