Hello and welcome to the Supermarket. It looks like a discount sale with numerous wonderful options. There is only one problem: Are you safe from Supermaneuverable Air-Defense Fighter Aircraft? Indeed, we hear the roaring sounds of the engine right outside now. With a top speed of 2,000 mph and armed with two high powered torpedo firing mechanisms, it is a formidable foe. But do not worry, with proper precaution we can arm your shopping cart to defend ourselves from this incredible danger.
