I think in the past I have mentioned that if you shop at Kimat Chinam, it is totally worth it to get their VIP card, because you get 2% off every purchase over 300 NIS if you pay in cash, PLUS you collect points, and when you get to 3000, you get a 30 NIS voucher. I love the 2% off - the 30 NIS voucher is way off in the distance for me, though, because in order to get 3000 points, you have to spend 3000 NIS in their store! And for those customers who shop at Kimat Chinam in Bet Shemesh or Petach Tikva, you can get a free ride home with your purchase of 250 NIS and up!
In addition, if you have their VIP card, you can print out some coupons on their website. Check it out!
