The Shop of Secrets) is the fourth studio album from Serbian and former Yugoslav rock band Bajaga i Instruktori, released in 1988.

[4] Prodavnica tajni was recorded in Radio Novi Sad studios, because, as Bajagić stated, the pressure of journalists was too big in Bajaga i Instruktori homecity Belgrade.

[6] Prodavnica tajni marked a slight stylistic change in the band's sound: the songs were simpler, without brass instruments, frequent on the band's previous releases, based on acoustic guitars and keyboards, and the songs "Plavi safir", "Vesela pesma", "Život je nekad siv, nekad žut" and "Ruski voz" featured folk music elements.

[8] Serbian critic Dimitrije Vojnov named Prodavnica tajni one of ten most important albums in the history of former Yugoslav rock, stating however, that with Prodavnica tajni "the most charming band in Yugoslavia went in a gloomy direction, and despite the fact that the band delivered some of their best songs, like 'Otkada tebe volim', on the album, it was obvious that they are going towards kafana [...] stopping by at ethnic music, again, not in their urban and charming way, but following the Oriental sound which is popular in kafanas.

From this point, which initially was not seen as alarming, as Prodavnica tajni was a legitimate pop product, Bajaga's energy seemed to dry up.
