Umbrella = 324 yen ($2.63 €2.45)

Since my son's umbrella was stolen in his school, my son temporarily used his sister's umbrella which is partially broken. My wife found a cheap umbrella at a shop, then bought it for my son. The price was 324 yen ($2.63 €2.45). The price was half of the previous stolen one. 

If the umbrella were stolen again, it would do less damage on us, rather than the case of an expensive one.
