Welcome to The Community of SC. SCOP stands for the scanning code of practice. If an item scans higher than the shelf price mention the SCOP and you should receive the it free if it is under $10.00. Over $10.00 you should get $10.00 off the correct price. Works in most stores except Zellers and sometimes the cashiers like to act stupid so you may have to push it. Look for signs around the till area of stores.
