Is the blessing of Shechiyanu recited upon purchasing expensive items?
The blessing of Shechiyanu on new items is only recited upon purchasing important clothing, or a home. However, it is not customary to recite it upon purchasing objects, including when one purchases [expensive objects such as] vessels made of gold and silver. It is not recited, neither by the time of purchase nor by the time of its [first] use. Practically, this is the main opinion that one should follow.
 Admur in Seder 12/5; Custom and opinion brought in M”A 223/5; Tosafus Sukka 46a in name of Rav Sharira Gaon who concludes the Talmud does not rule like the Mishneh; Rashba 1/245 that custom is to be lenient; Beis Yosef 223 that custom is to be lenient; Ben Ish Chaiy Rei 5; Kaf Hachaim 223/20; Piskeiy Teshuvos 223/6
Other opinions of Admur and other Poskim: In Luach 11/15, Admur rules a blessing is recited upon purchasing objects. So also rule: Mishneh Brachos 54a; Rif; Rambam; Rosh; Michaber 223/3; M”A 223/5; M”B 223/13; Igros Moshe 3/80; Some Poskim rule one is to say the blessing without Hashem’s name. [P”M 223 A”A 5]
 The reason: As these objects do not truly appear from time to time, and rather one purchases them one time for a lifetime. [See Tosafus ibid; M”A ibid]

Other opinions of Admur and other Poskim: In Luach 21/15 Admur rules a blessing is recited upon purchasing new Sefarim which are of importance and gives one joy, as although Mitzvos were not given for pleasure purposes, nevertheless one does receive pleasure when buying the object of the Mitzvah. So also rule: Opinion in M”A ibid; Mur Uketzia 223; Radbaz 3/412; Beis Yehuda 1 Y.D. 23
 The reason: As Mitzvos were not given for pleasure purposes. [M”A ibid]
