Other type of scam recently observed mainly targets customers of online auction sites such as eBay and Ubid.com .Modus operandi of these culprits involves misleading customers by auctioning the watch models at eBay or other bid sites with much lesser cost than cost which is mentioned in their websites.For example A particular watch model is priced $5000 as per the information provided by website but sold at a rate below $500 or less at eBay.
