Is there any additional feature that I can avail myself, to ensure my bid is the highest?
Yes, you can use the auto-bid feature for this. You can activate auto-bid by setting up the upper limit for your bid amount. By doing this, every time someone surpasses your bid, your bid amount will be automatically raised by the minimum incremental amount until the upper limit is reached.
You will be notified by SMS & email once the upper limit is reached. Please note that this feature is not available for closed auctions.
