A general population sample of 314 Australian respondents were randomly allocated to complete a contingent valuation survey administered by face‐to‐face or telephone (‘phone‐mail‐phone’) interview. Although the telephone interview was quicker to complete, no significant difference was found in values obtained through either method. Within each sub‐sample, respondents were also randomly allocated to the three different versions of the payment card (PC) questionnaire format: values listed from high‐to‐low, values listed from low‐to‐high and values randomly shuffled. The high‐to‐low version resulted in significantly higher values than the other versions. Further analyses indicate that the randomly shuffled PC version may produce the most ‘valid’ values.
