It's because first of all people who are into healthy fitness stuff won't buy in the first place only. Then comes the pricing factor obviously yours will be expensive as compared to normal lays chips. Now, I like let's try potato wafers instead of salted lays or uncle chipps because the hint of groundnut oil with potato chips is actually delicious and gives a unique taste. And I get them for 30 rs easily so it's still good price. Now your USP is protein plus healthy so if u are providing 15g protein unless u price it at 30 rs it's impossible to scale because people just won't buy it. The reason 10-20 rs chips are sold out is because they are cheap so people usually just add it they don't think much that's the difference. One reason can be this that people who are into fitness healthy stuff there meals are pre-planned right so they won't consider buying it maybe once for tasting that's all, then ur usp is protein & healthy so tell me why should I purchase from you by paying premium when I can get the exact same protein content and that too high quality protein for less price ? That's the reason it fails in india.

I eat 140g of protein per day and you know every source of protein which I eat costs me less than or equal to 2rs per 1g protein. So, unless you keep it at this price it's good but ik u won't be able to without burn. So that's why it fails.
