After reading the posts, all I can say is I've been very lucky. Only had 2 truck deliveries, both from Enco. 1st one was advertised as free truck delivery and the 2nd was with the 25% off and free delivery offer. I did not pay for lift-gate service. In both cases the trucking company called a few days prior to delivery, I mentioned that I was a residential address. I was told that R&L always sends a lift gate truck to residences. Drivers wheeled the pallet right to the garage (without having to ask). It never occurred to me to tip the driver, I like the cold soft drink idea.
BTW I bought a pallet jack from "Northern Tool", IIRC it was around $200. I use it all the time to move stuff around, including overloading it to move the mill and lathe. A friend worked in maintenance for a Grocery chain, they regularly scraped pallet jacks. He pulled one out of a dumpster, a "O" ring later and it works just fine.
