Anyone used conjoint analysis to price last-mile delivery options?

Conjoint is absolutely the right move here, not overkill at all. We ran a CBC study for a retailer last year with attributes like speed (same-day vs. next-day vs. 3-5 days), cost ($0–$9.99), and tracking options — around 300 respondents gave us really clean willingness-to-pay estimates. Qualtrics or Sawtooth both handle this well if you need a tool recommendation.
