Hi netpackpro,
This error is most likely being returned because you are selecting a domestic handling time in addition to choosing "Local Pick Up" as your only shipping service. If you make it so "-Select-" is showing in the "Domestic Handling Time" drop-down menu (which is the equivalent of not specifying a domestic handling time), I believe you will be able to post this item successfully.
If you are still unable to post this item, I recommend contacting our customer support team using the web form on the following page:
