Clerical Errors and Jewish Business Owner

If a business makes a mistake in your favor, you must correct it if the:
  • Business owner is Jewish, and
  • Error is more than 1/6th of the item's value. 
Note It is recommended to correct the error even if the owner is not Jewish.
Note In some situations, you must correct the error to a Jewish owner even if the error is less than 1/6th of the item's value—consult a rabbi.
Note If the owner (Jewish or non-Jewish) forgot to charge you at all, you must return the item or pay for it.
