To bid on Sam's Club auctions, become a member of Sam's Club, register at the auction site, and enter your credit card information. Find an item you want to bid on, click Bid Now, enter the amount you want to bid, review your bid, and click Submit. If another bidder places a higher bid, you can increase your bid until the auction closes.
To become a member of Sam's Club, go to SamsClub.com, select Auctions on the left side of the toolbar at the top of the page, and click on Join Sam's Club under Membership. To register for the auction site, go to Auctions.SamsClub.com, click on Member Sign In at the top right corner of the page, and enter your Sam's Club username and password. Add a credit card to your account, or check that your credit card information is up to date.
Once you are logged in, place bids on as many items as you want. After you submit a bid, it is final and cannot be changed. Alternatively, track an item without bidding by placing yourself on the item's watch list. Each item up for auction has a bidding history list that includes the usernames of the bidders, the amount they bid and the status of the item. Email notifications warn you when your bid is no longer winning.
