Many Lego stores have what they call the “Pick-a-Brick” wall, big bins of loose bricks in various shapes and colors. While it’s not priced by weight, there is a flat price for anything you can cram into a provided container. Most stores are very liberal about what you’re allowed to do to fit bricks into the container, too.
I’d totally buy Lego bricks by the pound.
