Some email users have lost money to bogus offers that arrived as spam in their in-box. Con artists are very cunning; they know how to make their claims seem legitimate. Some spam messages ask for your business, others invite you to a website with a detailed pitch.
Scammers use various ploys to part you from your cash and/or goods. Victims are harvested from auction sites (mainly eBay) and Sites that list classified ads for a variety of products, eg Craigs List, cars, horses etc. Victims are contacted by email and urged to send money/goods either within an auction or outside the system.
