[lbo-talk] God's ruling on good price-comparison bargain shopping

[Bryan Atinsky]

"Ultra-Orthodox Jews should prefer shopping in businesses owned by 
religious Jews, rather than by secular or non-Jewish owners, Rabbi 
Yaakov Yosef ruled. [...] However, the rabbi noted that according to one 
halachic view, it is permitted to shop at a secular or non-Jewish-owned 
business if the price difference between the latter and the religious 
competition is greater than 16.6%."
