Beautifying a mitzvah

Hi,

"Rabbi Chaviva said in the name of the sages of Babylon: If a person purchases an item for a mitzvah and then finds a nicer item to purchase for that mitzvah, he should spend up to 1/3 beyond the value of the original item to purchase the nicer item."

(Talmud Yerushalmi, Peah 1:1)

Have a great day,
Mordechai
