The first point is to find the best buy digital camera with the highest resolution you can afford which will normally be at least 2 to 3 megapixels (2 million to 3 million pixels). If you will only output pictures to a computer monitor (for viewing, Web page use or e-mail) then the best buy digital camera will be one with a 640-by 480 pixel resolution and it will provide very satisfactory results. There are very few genuine best buy digital camera packages with high-resolution and the specified resolution may only apply to software interpolation rather than the true optical resolution. To print photographs on a good (at least 720 dots per inch) color printer you will need to look for the best buy digital camera with a high resolution.
Many retailers advertise their best buy digital camera as one with a plastic lens. It is better to buy a digital camera with a 100% glass lens for the best pictures. You should also look for the best buy digital camera packages with the most RAM that you can afford. The more RAM the camera has means that it can store more pictures and does not require downloading or erasing them as often.
When you are evaluating the best buy digital camera offers you need to compare optical, as opposed to digital, zoom capabilities. This is one of the most frequently used features of most digital cameras and you need to be sure that you have the capability to take the type of close-up shots that you want to.
Another issue that needs to be considered is whether the best buy digital camera offer actually includes the accessories that you require. If you find that you are going to have to purchase additional cables and software to be able to connect your digital camera to your computer then it is not going to be the best buy digital camera that you thought it was.
Finally, ensure that you have accounted for any shipping costs before you make your final decision over which best buy digital camera you purchase. A lot of unscrupulous retailers will advertise a price for a best buy digital camera but then charge high shipping costs.
