As with other acts of vandalism such as licking ice cream, crushing cookies, opening packages and other foolishness, this will necessitate the store removing and destroying product that someone will have to pay for. Since you have announced your intent and provided evidence of your contemplated crime you will likely get caught. As each sticker will be a separate count of vandalism, it would probably be wise to consult with a lawyer before you act rather than after you are caught. Both civil and criminal liability will be at issue.
