Chapter 266, Section 30 of the Massachusetts General Laws provides a clear definition of shoplifting. The crime is considered if you have taken an item out of the store with the intention of not paying for it.
Another thing that can also be considered a crime is changing the price tag of any item in the shop intentionally so that you might get the chance to scam the business by paying a lower price.
