Basically when you see someone selling an item and it says a/w $60 this is just an example, it means he will take that ammount for the account, like a buy it now auction.
The autowin is basicaly the buy now price, it is what the seller will happily sell the account for. if someone bids/offers the autowin price, they will most likely accept. I am crap at explaining ~ um if you have ever used ebay you can see that on auctions there is like a buy now price, which you pay to get it startight away without the bids, an autowins like that
