Digital photography gear can be quite expensive, so it makes sense to save money if you can. Even a relatively small saving, like 10% could result in smaller dent in your wallet.
For purchasing new photography equipment, it is often cheaper to purchase online than in a bricks and mortar store. This is because online shops don't have the overheads of having to pay the high rental costs for a shop front.
There are a lot of websites selling cameras and lenses online, so how do you find out which is cheapest? Camera price buster US and Camera price buster UK both gather prices on camera equipment from a range of retailers, and then list the cheapest on their website. You can also view prices of an item on a graph, to see whether the price has been dropping or increasing lately.
Another good comparison website is Google shopping. Though Google is not quite so good as you will often find their listings filled with hundreds of accessories and unrelated items. If you are searching for a camera or lens, sort the items by price. Then flick through the pages until you find where the listings for the item you want actually start.
