Merchant Behavior in the Marketplace
A merchant may buy from five threshing floors and put the produce into a storage chamber, or from five winepresses and put [the wine] into one jug, as long as he does not intend to mix them [for purposes of fraud]. R. Judah says: A storekeeper should not distribute parched corn or nuts to children, for that accustoms them to come [only] to him. But the sages permit [it]. And he may not lower the price. But the sages say: Let him be remembered for good [if he lowers the price]. He may not sift crushed beans, according to Abba Saul. But the sages permit [it]. But they agree that he should not sift them [only] at the entry of the storage chamber, since he would be a deceiver of the eye. He should not beautify what he sells, whether humans, cattle, or utensils.
