What does "as-is, where-is" mean at a government auction?

It means the item is sold in its current condition, with no warranty, no returns and no repairs, and you collect it from wherever it currently sits.

"As-is" covers condition: if the vehicle does not start or the laptop does not power on after you win, it is still yours. "Where-is" covers location: the seller does not deliver, so pickup or transport is your job and your cost.

Almost all government surplus sells on these terms. Inspect before bidding when you can, and work the cost of getting the item home into your maximum bid.
