Are prices on CD always as listed, or have you ever been able to bargain for a lower price? Is this possible online? A lot of times I felt the price of a CD on an online shop was inflated if it was the same as the one in a real store, especially since you have to pay shipping on top. Being a broke-ass student, I've been able to bargain in clothes stores sometimes but I was wondering whether this is possible with online metal purchases.

Depends, smaller distros will usually bargain a bit, you can usually get a free CD or something, last time I got a free zine. If it's a bigger store, don't even bother. Basically, Nuclear Blast size or up is the death zone of bargaining.
