Return Policy at O'Reily's. Google search came up with thread which didn't answer my question really. I don't know what their policy is but I needed a part that was $109. and wanted to get partial credit with some brakes that I found out I didn't need after all. Bought them at another O'Rielly's in San Francisco less than 30 days ago, never opened them and Oakland store would not take them back, not even with credit. Never heard of a franchise not taking back something from another store. Annoying, told them forget it I'll go elsewhere
