Is this an RTC auction?
Auctions can be moneymakers, but you might start with farm auctions and estate auctions before you buy gov't stuff sight unseen.
Find something you know about at an auction (everyone knows something about something right?) and never get caught up in the mad bidding that occurs. Be patient, and grab only the best deals that you are sure you can profit on.
For example, a friend of mine buys appliances at auctions, once he got a refrigerator, 2 ranges, a small air conditioner, 2 washers, and a dryer for $1. Not $1 each, but $1.00. No one else bid on them, they were ugly brown and avocado colors (he repainted them). He did quite well on the resale.
This is kind of a side business for him, he has a paint booth and a large trailer to haul this stuff.
