Hi man, it's easy, there are many websites in Israel that sell appliances such as payngo, wallashops or lastprice. The only problem with those websites is that they are 100% in hebrew so it will be hard for you to purchase. I recently discovered a website, 3 months ago, that sells big appliances (fridges, tvs, washers, ovens...) in Israel with a website in English, it's Zabilo. They also have good prices and service, so that's my best solution:
