How do you test price sensitivity for a new snack product?

Conjoint is definitely worth it for a premium launch — the price-feature tradeoffs it reveals can save you from mispricing by 20-30%. That said, if budget's tight, a simpler Van Westendorp Price Sensitivity Meter survey (50-100 respondents, 4 questions) will get you acceptable/unacceptable price ranges fast. I'd pair whichever you choose with a small in-store or online test at 2-3 price points if you can swing it.
