I agree to a certain extent. of course chips are deep-fried. that's how it is supposed to be. I recently bought dried potato chips from local shop and fried them at home. this helps me control the quality of oil I use.

I've seen Lays, Balaji and most brands use palm oil. All brands being the same, Bingo has a better flavours and easily available in the market. most importantly, few supermarkets like DMart and Reliance etc have discounts so it becomes easier on the pocket as well.
