Can only go down to 3 and would like the option for 1 second. Thank you for this service, it is great.

Hello Nick,
Thank you for the suggestion. We don't put the 1-second lead time in the Preferences because it should only be used for higher-dollar items where ties are likely. In those cases you want your bid to come in earlier, around 5 second.
Thanks and we might consider adding it with a disclaimer that shows below the selection.
