I bought a grape flavor toothpaste for my son at Seiyu. Its price is 162 yen ($1.59 €1.18) for 70 gram.
Kids Socks = 257 yen ($2.52 €1.88)
I also bought a set of my son's socks for 257 yen ($2.52 €1.88) at Seiyu with a discount price. The original price was 580 yen+tax. The set includes 5 socks. Two of them are white socks. He has to wear white socks when he goes to the school, because of the school regulation. He will wear black and gray socks on weekends.
You can see a discount tag "Yen 238". Actually we need to pay tax in addition to that price.
