Ok Ok I'm not a fan of Harbor Freight at all! But they do sell chip brushes (disposable paint brushes) very cheap.

I had bought some at Lowes and paid $1.27 each. Checked online and found HF had them for .27 each. Needless to say I took them back to Lowes and made the trip to HF. I'm not feeling too bad about buying them from there, Since I feel like everything there is disposable anyway
