Hi, yes but if you are using them to direct custom to your store and store inventory format listings their active life span is unknown, i.e. they may be snapped up in a day or so.
If you make them 10 day listings starting at the store price for instance they will be directing custom for 10 days. A potential plus point is that bidders may compete and raise the selling price and give you more cash as well
Set the end time to a preferred day to suit your customers peak viewing times for maximum sale value
