One doesn’t need to spend an arm and a leg to be frum.
Clothes don’t need to be designer. Meat can and should only be eaten on Shabbos and Yom Tov, even if then. A vegetarian lifestyle is healthier and cheaper, anyways. You only need to worry about maintaining 1 set of kitchen equipment and plates, and another set for Pesach.
I see Judaica for cheap in different places, like Closeout Connection and Amazing Savings.
I believe that instead of wasting money on luxuries, we should give more to the needy and reprioritize.
