Unfortunately, your question was cut off before you could provide all of your information. If you were charged with "shoplifting" or some other form of theft offense, you should definitely retain an attorney to represent you. If you were not formally charged, I suggest that you take a wait-and-see approach. If you do not get charged, then you will not need an attorney. Please bear in mind, however, that in New Jersey the store has the right to demand a "civil penalty" even if you do not receive a criminal charge, and you may get a letter from Costco's attorneys demanding this penalty.
