I would just use
Buy Computer Parts, Computer Hardware, PC Parts at Best Online Computer Shop - DirectCanada, free shipping on orders over $300.
Its owned by the same company (NX Group)
What are your componants and prices? Because you might be able to find better prices for each componant at different places, price match at NCIX and it would make up for having to pay for shipping there.
But I'm sure bestdirect is fine, if your set on ordering from there
edit: damn EagleEye beat me to it
