Retracting bids
He is not allowed to retract his bid per eBay's rules.
You can retract a bid or a Best Offer for the following reasons:
You make a typographical error and enter the wrong bid amount. For instance, you bid $99.50 instead of $9.95. If this occurs, enter the correct bid amount immediately after you retract your bid. If you do not place another bid, the retraction will be in violation of eBay's policy and could result in your suspension. Please review the retraction guidelines if you need to retract your bid.
The description of an item you have bid on changed significantly after you placed your bid.
You cannot contact the seller. This means that you tried to call the seller, but his or her phone number doesn't work, or that you have tried emailing a message to the seller and it comes back undeliverable.
There are people all over eBay who have bid on items but end up finding the item somewhere else after they have been outbid. Many times, I have seen items driven up in price by people who want an item but then they find a newly listed one on eBay to bid on or just decide that they don't want to bid any higher. It looks like Skip REALLY wanted the vacuum as he was going to take out a loan to buy it but ended up making a deal with someone else who was going to bid "to the max" for hte blue on one eBay. It's no crime and it doesn't bother the person who is evidently bidding and selling the brown one to Skip.
