Hey mate, it is not obligatory you will get it on Sundays. If you want to include Sunday deliveries in your subscription, then you are looking at an additional $12.50 totaling $40. I recommend to check out this cool resource about does mail get delivered on sunday pirscapital.com/blog/does-usps-deliver-on-sunday/ to get a clear picture of how it works. I have found a lot of useful information there by the way. Good luck
Sunday in Israel is a normal working day. Most services work a six-day week, Sunday to Thursday, with Friday being a shorter day because of the Sabbath, which starts at sundown on Friday evening.
Due to cutbacks and various services that are far more efficient, the Post office no longer delivers mail daily, sometimes even only once or twice a week in some areas.
