Round 2 of Donnerdeal's Black Friday sales have begun, which will last through November 30th. You can save 30% off pedals with the code B8F6TFBE50M0
Donnerdeal is also offering a free pedal cable with each order, and "$20 Gift Card for Custome's Order（During 23th-30th） valued $300", though I have no idea what that means.
And here are a few more items on sale that aren't pedals, but could be useful:
DP-2 power supply - $35
DB-2 pedalboard (20" x 8") - $50
DB-3 pedalboard (20" x 11.4") - $60
