How do i get into an online government auto auction for free?

There are many ways. You can go to GovDeals.com, GSA auctions, USA.gov and other areas to get more info on the area of gov't auctions. Now as for free, it is a little more tricky. But there are sites such as govliquidation.com for free alerts and myhonestmechanic.com for more free government auction advice. I really hope this helps. Now if you are involved in reselling these items you will need good online auction software to sell the items in order to make a profit. Many folks do this and have indeed made quite a profit. There is a lot of info available online. Just keep searching.
