1) The most important step you can take to ensure you get the best value is to compare prices, on the internet there is almost always a more competetive price and its only a few clicks away if you know how to find it. A good way to do this is to search the exact name and model in a search engine with the keyword buy, this should give you a list of sites offering these same products then its left for you to do the research.
2) Buying in bulk, whilst this may not possible in all situation buying in bulk is often possible and cheaper. If you have friends or family who may also want to purchase the item check with them first and you may all get a better price. E,g how many people would be interested in a discounted Ipod at the office getting everyone to pitch in can substantially drop the price. Look for "Volume Discounts".
