boycotting

upon buying from certain places, money is indirectly given to israel, some brands are: nestlé, l'oreal, amazon, burger king, kfc, mdonalds, etc.. find more on https://www.ethicalconsumer.org/ethicalcampaigns/boycotts 

and if you're at the store, and you aren't sure if the item is to be boycotted, you can use the "no thanks" app to scan the barcode; from there it tells you if the brand supports israel
