Shehechiyanu in Mourning

Hi,

One who is in mourning does recite Shehechiyanu for occasions which are not of his creation, like Chanukah and Purim. However, he should not recite Shehechiyanu for situations of his own creation, like purchasing a new fruit or new garment.

(Rivivot Ephraim 1:20)

Have a great day,
Mordechai
