Non Binding Bids Policy: In most product categories on eBay, when you place a bid in an auction it's considered binding – when you win an auction, you're agreeing to complete the purchase. However, there are some categories where bids don't create a formal contract between the buyer and seller.
For motor vehicles and real estate, bids are considered non-binding. When you bid on an item in these categories, you're expressing a strong interest in buying the seller's item, but no formal purchase contract is created if you're the winning bidder.
A non-binding bid is a bid that shows a buyer's interest in purchasing an item, but it doesn't create a formal contract between the buyer and the seller. All bids made in the Real Estate and eBay Motors vehicles categories are considered non-binding.
