So i added up all of the parts including the Cpu, motherboard, ram, storage, case, gpu, and power supply which all adds up to 416.93 at least that's whats it says. But when I add everything in checkout (Buying some parts from different sites) it comes out with 476.92 and i doubt that's shipping.

I'm buying the cpu and power supply for $144.98 at NCIX US
The RAM and hard drive are $98.98 at amazon
The case and gpu at newegg which is 179.98
and the motherboard for 52.98
which all adds up to 476.92. Someone please help me, am I doing this math wrong or should i buy everything in a separate checkout? Thanks.
