Here's more stuff from the site:
[They are auctions, but you only need Kellogg's Kash to cover the min. bid. Anything over that you can put on your credit card. It also looks like they post the current winning bidders and what they're bidding. I haven't looked at it all too closely because I don't eat any of those cereals.]
Q. Is there a minimum bid for auction items? Back to Top
Yes. Each item in the auction area will be subject to a minimum bid, which will be posted at the site. Remember that each Official KELLOGG KASH Certificate is worth $1.00 toward the purchase of an Auction Item at the online auction, and has no other cash value. You must have enough Official KELLOGG KASH Certificates to cover the minimum bid.
Q. Is there a maximum bid limit? Back to Top
There is no maximum total bid, but you must bid at least $1.00 (One Dollar) more than the previous bid to continue bidding. You may not bid more than 25% (Twenty-Five Per Cent) above the last bid for all Auction Items on which the bidding has exceeded $4 (Four Dollars). Non-conforming bids will be rejected.
Q. What if I don't have enough Kellogg Kash certificates to cover the minimum bid? Back to Top
Sorry, you are ineligible to bid on that Auction Item. You must have enough Official KELLOGG KASH Certificates to at least cover the minimum bid amount posted for the Auction Item. We reserve the right to disqualify anyone who fails to return the minimum number of Official KELLOGG KASH Certificates listed for the Auction Item, refuse to redeem the Auction Item, and close down your account.
Q. What if I don't have enough official Kellogg Kash certificates to pay for the auction item in full? Back to Top
As long as you have enough Official KELLOGG KASH Certificates to cover the minimum bid amount for the Auction Item you want, you may participate in the auction. If you are the successful bidder, we will charge the difference between the number of Official KELLOGG KASH Certificates you return (each Certificate is worth One Dollar ($1.00) towards the purchase of Auction Items at
www.kelloggkash.com) and your total bid amount to the credit card you provided when you opened your account.
