In the USA, the Friday after Thanksgiving is known as Black Friday, because it's a) the busiest shopping day of the year, and b) because it's usually the first day of the quarter when stores go from being in the red to being in the black (making money).
Along with Black Friday comes incredible deals that we get to pass along to you! Throughout the day, we'll update this post with theremin-related deals we find in the Ether. Stay tuned, and enjoy the savings!
