If you sell at $35 we will clear it.
Why would we clear the food at $36? There's no profit to be made in doing that. By clearing the $36 food, we would ensure that no one sells at $35, and thus, no profit can be made by any food clearers. By not clearing the $36 food, we ensure that some people will sell at $35, and thus provide profit for the food clearers.
To clear the $36 food just does not make sense.
