Don't forget that if the company is stationed or has a warehouse in the state you live, sales tax applies if the state has one. Shipping charges also apply.
Nope, don't get sales tax here :good: sorry, you could drop the sound card any use onboard. I've never heard, nor used an Audigy but I've also heard some bad things about them. I'm pretty much OK with anything besides a creative 16-bit
Shipping would apply for sure, but that depends on the items. Some stuff Newegg doesn't charge for (not to mention other online retailers). Cases and monitors are pretty much guaranteed to have fairly meaty shipping charges on them, so you might want to consider picking both of these up locally.
