Remember to select a reasonable bidding duration. I usually do a 7-day auction to build interest and allow more time for people to see it. I always ensure bids end on a weekend, usually a Sunday night, when more people tend to be sitting down using their phones, and you might get bidding competition.
If something is in demand you’ll get lots of communication from buyers, make sure you reply quickly and with as much information as possible. There may be questions about the product or even offers to buy it sooner than the end of the auction date.
I’ve given up on buying an item before, if the seller doesn’t respond to your questions, or doesn’t answer something you need like the dimensions of an object.
Try to hold out until the end of an auction, if people are keen to offer before, it is normally for a good deal for them, although you’ll have to take a risk that it might be the best offer you get, I’ve never had this happen though. Remember if you end an auction early for a cash offer eBay might ask for fees or give you a breach of selling contract warning as they don’t want to miss out on selling fees. If you do want to take an early offer you could agree on a price with the buyer and switch the listing to a buy it now auction price on the system and coordinate with your buyer to select that option, that way all fees go through eBay as normal.
Don’t forget to tell the buyer immediately when items are dispatched directly or on the platform’s app. It adds to the trust that their item is on its way and avoids any chase up emails asking you where it is. Don’t dispatch until they have paid. If it is ‘collection only’ and has been collected then update the app so all fees can be processed and funds transferred to you.
