In my experience, there are two factors that determine how much you should be paying for brick.
First, if you want all of your bricks to be the same color/texture/etc. You are likely going to pay a premium. As Dale suggested, a lot of people are giving away bricks, but they often are giving away those bricks that are left over after a project...or if you're lucky the project they intended to do but never got around to starting.
The second factor is how soon you need the bricks. If you are willing to check Craigslist every day for the next couple months for brick ads, you should be able to easily get enough bricks for free or near free. For really nice bricks I would sometimes pay $10 or $20 a truckload. If you need them by this weekend, you'll probably have to buy them from a retailer.
Also, for a 6-7 foot high wall you might be entering the land of "permits required" so I'd suggest checking on that before you have 10 tons of bricks sitting in your driveway.
