10. The URL is suspect
Looking to cop from such illustrious outlets like "givenchy-gear-for-less.com" or "supreme-limitedproducts.com?" Think again. Most brands that offer e-commerce do so from their own trusted websites with simple URLs—or verified stores also with easy URLs, like barneys.com and karmaloop.com. Check the favicon in the browser too—it's that little icon to the left of the URL. Does it look legit?
