Tips from locals
Not necessairely cheaper than Monoprix but has all the nessecities. Great organic section for fruit and vegies
It's the biggest and cheapest supermarket of the neighborhood. You can find everything there, but I usually only shop for the essential stuff, and buy my vegetables/fruit/meat/fish on the market (Wednesday and Saturday mornings on Cours de Vincennes.)
