When looking at a product online, pay attention to how it is presented. This includes information and images.
The very first thing is to determine whether the images are actual, unedited photos of the product or whether they are stock images. Don’t pay for goods you haven’t seen as you might not be getting what you paid for. The product description should have more information on the condition, but actual photos are often the best determiner. Consider whether the item is new, in excellent or in good working condition? Does it show slight signs of use or marks of harder work?
Next, read the product description. Cameras, lenses and accessories all need complete information on the make and model of the item. Make sure the information provided corresponds with the suppliers’ online product listing (Canon/Nikon). Also, avoid adverts with broken English.
Finally, note what is included. Is it an entire kit or is something missing?
