How long does it take for post from UK to reach Ireland?

Answer 1

Some, depending on where you live, come the next day if the mail had been posted before noon the previous day. Others can come anything between 2 and 5 days, also depending on your loaction (whether you live in a town or city, or the country). Busy times like Christmas can influence the time you await your post by maybe a day or 2 longer.

Answer 2

It would take about 10 days give or take depending on which part of the States your either receiving or sending from.
