most pc builders mark up the prices on products they sell.
if you want the lowest prices then build the system yourself. honestly with supervision a 10 year old can assemble one.
if you dont know what you want post in the builds section
as far as razer products.. the deathadder works fine as a mouse if the rubber surface appeals to you. see my other posts on that matter as i have one. another good choice are logitech mice.
as far as keyboards make sure the razer doesnt have a rubber finish. personally i'd suggest a better keyboard like deck, das, or another mechanical board. for rubber dome boards its hard to beat logitech for value.
