To get things out of the way first, for those not familiar with Moe Day, the MangaGamer team have provided a detailed explanation what makes this day so special:
Moe Day (moe no hi) is a bit of Japanese wordplay. Taking place on 10/10, Moe Day is 十月十日 in Japanese. Written traditionally, with the date read right to left vertically, you get a shape that visually resembles the Japanese kanji for moe!
It may not be an official holiday on the calendar, however this isn’t stopping MangaGamer from doing something special for it. For the next 24ish hours (From Midnight until 11:59PM US Eastern Time on 10/10/2014), they will be slashing 25-50% off a number of their visual novel products from Japanese studios including Circus, OVERDRIVE and Score.
