Just be prepared to spend a long time in security. From my recollection of visiting Tel Aviv for work a few years ago, there was tight security and everyone got asked questions about where they had been and what they had done. Do not get upset if it happens as they are just doing their job and not necessarily picking on you for anything specific. We all left the city with souvenirs and I don't think anyone was taxed as no one had spend loads of money. This is from one website:
Goods purchased abroad or at the Duty Free, provided that the value thereof shall not exceed $200; the quantity of the goods shall also be limited to 1 litre of alcohol and 2 litres of wine, 250 ml of perfumes, 250 grams of tobacco (1 carton) – which are exempt from customs duties.
Just be aware - I bought what I thought was a lovely watercolor picture. Years later, the frame broke and I bought a new one to replace it. When I took the "painting" out, it turned out to be a cutting from a magazine. It made me chuckle!
