Where To Get A Bumper?

[Lord Odin]

I was involved in a minor fendor bender and the plastic part of my bumper has been damange. It's the top piece, not the lower part with the fog lamps or the center, metal bumper. Just the top cover piece. Looks easy enough to replace, so I thought I would do it myself. Where can I get that replacement part from other than the Chevy dealership, where they would probably rip me off? What's a good vendor for parts like this for my truck?

I've used LMC Truck before for some parts. Not sure if they're the cheapest?
