Where are The DVDs?

A series of Japanese comedy movies, Otoko wa turaiyo,It's tough being a man,is one of the most popular movies in Japan.I love the movies very much too.In fact I have watched all of the stories,amazingly the forty-eight films is a Guinness book record, on DVDs.It took a year to watch the whole of the DVDs and it cost about 15,000yen for rent.I would dream of having the DVD set.A few months ago I found the complete DVD set at a used DVD shop.I needed to pay120,000yen for a new one.At that time I could see 68,000yen on the price card and I realized it used to say 80,000yen initially.I was eager to buy them but they were too expensive for me.I thought no one would buy them because of such a high price so they would cut down the price soon.I decided to wait to buy them.I waited for two weeks.They were still there.Another two weeks,oh,they were gone!I shoud have bought them immediately!
