On the flipside, that is why I sell most of my surplus auto parts on local craigslist. I don't know a way to ship at prices which big guys and especially Chinese sellers get. I don't care to deal with buyers who fuss about a shipping price, but can't tell me how I can ship it them cheaper.
On the flipside, back ~2005 I got a Tremec 6-speed via a shipper (FedEx, forget) but not the minivan transmission I had bought. I kept trying to return it to them, and they picked it up once, but they phoned saying "not properly packaged". Told them that's how it came to me. I said if they returned it, I would sell it, and they returned it. Sold it for $700 on ebay (cheap for a Tremec) and only cost $70 to ship it from CA to AZ via DHL air. I just put it on the conveyer belt w/ label at the nearly DHL air facility. All others wanted >$300. Soon after, DHL stopped local shipping in U.S. BTW, the used minivan transmission I bought showed up unannounced 3 months later in my driveway.
