Big sale in Finland

Now in Finland the shops are already started the summer sale,every year after the midsummer day the shops will start the sale. Well, it is a little bit early for me to call it summer sale,but it is real. Yesterday I went to some shop and saw much more people there choosing things. Now in the begining of the sale some things are about 30% off,later it will be 50% off. But really good things will not change price.
Here every year about 2 times this kinda sale,one is after new year and the other is after midsummer day. But in China,there are at least four times sales : after the chinese new year, during the May labor day,summer end ( about in August),during the October national holiday.
I do not know about other countries,but when these times come, I all always can see lots of people in the shops!
Finnish means "on sale"
