Lisa Kim Barnett, aged 42, of Marathon Road, Douglas, has denied attempting to post £5,000 in cash relating to criminal activity to an address in Liverpool.
A package intended for an address in Walton was intercepted at the Post Office sorting office on June 11.
It was found to contain a box of Milk Tray chocolates with £5,000 in cash hidden in the bottom of the box.
Deputy High Bailiff Chris Arrowsmith accepted summary court jurisdiction and a pre-trial review will be held on January 7 next year.
Bail continues in the sum of £500 with a condition that Ms Barnett live at her home address.
