One of the most prevalent types of email fraud comes of the form of offers that are too good to be true. The fraudulent offer typically features a popular item or service, at a drastically reduced price. Most of these are just an attempt to get your credit card information and if something seems too good to be true, it probably is.
Another type of bogus offer affects people who use Ebay, Craigslist, or any other online retailer for selling their belongings. The typical scam is that a person will contact you offering to pay the full amount, or even more for a rush delivery, but they refuse to pay you until they receive the item for inspection or some other reason.
