If you land at Ben Gurion airport and oops...you've forgotten something at home or need butane stove or anything, these are the most convenient three places to buy stwff (Welsh for stuff): Rikushet in Azriely center: take a train from the airport to Tel Aviv Hashalom (15 minutes). Go up the stairs to Azriely center.
If you go north to Kiryat Shemona there is a Rikushet store there (10 minutes walk from the central bus station).
If you go to Eilat there is a Rikushet store in Eilat too.
Lamtayel OK, but the numbers of stores is limited....
