"How many of you have picked up an item at one of the big box stores, marked $10.00, and when you get to the checkout the checker scans the item, it beeps $7.00. Do you stop the checker and say "wait! I need to give you another $3.00 for that gizmo"?
Done it several times actually and told them that the price on the shelf was $10.00; only when they stated that the shelf price was a mislabel do I pay the $7.00.
Equivalent would have been for the OP to say that he agreed to $59,000 and ask what happened to that agreement and why the price was $9,000 lower. Simply asking if the write-up is correct without asking what happened to the bargained-for agreement on price is insufficient, in my view.
...but we do need to move on.
