Thanks for the kind replies.
Shipping turned out to be a real challenge. FedEx was my first go to because the buyer had a FedEx account. Over the course of 3 days and several phone calls to FedEx, speaking with a half dozen people, I got $ numbers from $180 to $2,200 for shipping! Unfortunately the lowest quotes were not quotes but guesses, and when it came down to it the cost was over $1,000 with FedEx.
On the recommendation of several forum members I called Fastenal, and got the lowest FIRM quote from them at $422. That would have required me loading up the crate and driving an hour away to the Fastenal shipping site, and the buyer would have had to pick up the crate from Fastenal near them.
YRC freight is a company I have used before to ship medical equipment freight on a couple of pallets, and the buyer had a friend with a YRC account. The online quote was $700, but through the account holder, they were able to get it down to about $450, and that included a lift gate truck to pick it up.
YRC had me stuck at my house from noon to 4:45 waiting for them to pick up the crate on the 23rd. When I called at 4:45 I was told that the pickup had been pushed back to the 26th! It would have been great if they would have let me know!
Once the 26th rolled around, I didn't wait to call. The first person I spoke with said my pickup had been rescheduled again, but I asked for the dispatcher and he said that they would pickup as planned, around 5-6pm, and the driver would call about a hour before he got here. The last drama was the driver informing me that he would NOT drive onto my property, even though I have a rock driveway that the truck can't hurt, so my wife and I had to get the crate down the 300 foot long driveway to the street! Fortunately I had the crate on a Kobalt 4 wheel dolly, and we were able to roll it across the rocks in the driveway.
YRC has been very good about emailing tracking information for the shipment progress, and I am glad the seat is going to a good home, and my crate will get it there safely.
