How do I place my eBay store on Holiday mode?
Going on holiday? Use your eBay Store holiday settings to make sure your buyers aren't disappointed by buying items and unexpectedly waiting a long time to receive them.
When you turn on your holiday settings, we display a message in your listings letting your buyers know you're on holiday. You can also add a customised message to your eBay storefront.
