There's no doubt that trust seals work. We've used ScanAlert and Trustguard on a number of sites, and there's definitely an increase in sales when you put the seals up. But other than provide a graphic for you to put on your site and give your customers a warm and fuzzy, what exactly do these sites do? We paid $400 to Trustguard and they made a phone call and sent us a letter to verify that we're a real company. What are these sites doing that justifies this amount of money? Where are the companies that provide a more reasonably priced service? Is the low cost provider really hundreds per year?
