This store is pretty small, but it's very close to the University of Tsukuba campus, so many people use it. It has a special discount system that sounds a bit complicated, but I have been assured that it makes sense once you've tried it out. All OLD videos are 100 yen on the days that end with the same number as the month (in July, that would be the 7th, 17th, and 27th). You get the videos for 7 days in January, February, March, November and December, and for 3 days in the other months. Then, seven days after those days (eg. 14th, 24th, and ??), you can rent NEW videos for half price for 3 days. In certain months, this creates a perfect cycle so you can rent old videos for one week, then when you return them you can rent new videos for three days, then when you return them you can rent old videos again, etc. Neat, eh?
