Things to consider when bidding for an item on Ebay:
Do not purchase an expensive item (especially in electronics) if it contains several of the following:
Price is "too good to be true" and/or great price offered PLUS free shipping.
Auction description appears to be cut and pasted from a Web site, is excessively long (so as to be confusing) and the photo of the item is not of an actual item; rather it is a stock/catalog photo.
Seller's feedback is primarily as a buyer or those items s/he normally sells are not of that type/price range.
Seller's feedback is primarily as a buyer or seller of inexpensive items (recipes, coupons, eBooks, digital photos, etc.) and is now selling expensive merchandise.
Seller requires Western Union as only method of payment. Red Flag! (Always pay for expensive items through PayPal using a credit card for optimal buyer protection).
Seller is not located in U.S. or their ID/listing states U.S., but the seller requires payment be wired elsewhere.
One or three day auction for expensive items is another red flag! Most legitimate sellers want exposure (more bang for their buck) and will list their auctions for five, seven or 10 days.
