Not always true I just got screwed as a buyer. Bought a part that was not as described it was broken and welded. I had to ship back and got a refund for part plus original shipping. So the seller says sorry for not looking part over better before listing but no money for return shipping being he lost original shipping cost. Here I sit with no part and out 17.45 cost for return shipping. So sometimes the buyer gets a screw job. I told him I will leave a negative feedback and he says oh well I am a power seller go right ahead.
