There is also the option of making your donation a "Buzzer Beater."
What that means is that (up until about the last hour) you can donate the amount that you want to donate, and click the "Buzzer Beater" option. Publically, only half of your donation will be visible, but at 7:45PM, the rest of your donation will go through. Currently we can see that we have 9 Buzzer Beaters pending for 7:45 tonight, but we can't tell which donations those are attached to.
It definitely makes the last 15 minutes intense!
