I used to make my Ebay listings available to EU countries, but during the lockdown I changed them to UK only as the post was getting so delayed that I didn't want to get into trouble for late delivery or have people waiting ages for an item.
I use Royal Mail, not couriers. What's the situation like at the moment with posting to EU countries - is it arriving on time?
My post is arriving fine but I know it's been different in different areas.
