All sellers are now required to specify a domestic P&P for deliveries within the UK. New listings without a specified domestic P&P will be blocked.

There are limits to P&P charges in certain categoriesfor deliveries within the UK. New listings for which P&P charges exceed these limits will be blocked

Flat-rate P&P costs
When you select 'Flat: same cost to all buyers' in the Sell Your Item form, you decide the postage and packaging costs and which services to use. This option enables you to enter flat costs for UK and international delivery. If you are selling more than one item, you can enter a postage and packaging cost for each additional item a buyer purchases. The cost you enter will display on your item listing. Your buyers will be charged the cost you specify when they pay for the item.

Note: You'll also be required to specify a dispatch time when you list your item. If you do not specify a dispatch time, eBay will select a default dispatch time for you.
