I always pay attention as stuff is scanned, it's amazing how often the check out zombies double scan items. I especially pay attention to items on discount on the shelf as they don't always scan at the discount price at the checkout. Woolies especially, because you get it for free if it scans wrong. If I see the item is discounted in the junk mail and at the regular price on the shelf, I'll grab 2 because when it scans wrong you get the first one free and the second at a discount. Sometimes it takes a bit of spirited discussion with the checkout zombie to make it happen but once the supervisor or manager gets involved they have to honor the policy.
