On eBay, bidding does not mean that you will definitely successfully purchase the item. Even if the buyer bids and wins the auction, the seller still has the right to decide whether to sell the item.

In some cases, the seller may decide not to sell the item due to the condition of the goods, the terms of the transaction, or other reasons. Therefore, buyers should contact the seller before bidding to confirm the availability of the goods and the details of the transaction. In addition, eBay has an obligation to the seller to fulfill the transaction, but it also requires buyers and sellers to abide by the transaction regulations and fully understand and negotiate the transaction. Ultimately, negotiation and cooperation between buyers and sellers are the key to ensuring the success of the transaction.
