Ebay estimated delivery times are just that ~ estimated.
Items may take longer to arrive during seasonal holidays.
e.g Christmas ~ Easter ~ Bank Holidays ~ During postal strikes or times of extreme weather conditions.
When my shop is closed for personal reasons there will always be a large notice at the top of my shop page.
This will remind you when I am away and when I shall be returning.
Ebay will also place their own notice on the top of each items selling page and it will show again when you make payment ~ this is very small.
Please be aware that when I am closed for personal reasons you will still be able to buy items from the shop but they will not be posted until I re-open.
