Just upgraded to 1.3.9.f

I sell pet food. Some of the frozen items are too large to ship in coolers with dry ice. Some of them require next day or 2nd day shipping due to extreme perish-ability.

I'd like to be able to display the non shippable items in the cart so that local customers can see what we have available and or can order them for store pickup/home delivery only.

I would like to be able to force overnight/2nd day shipping for the highly perishable items only.

I've put notes in the product categories section and on the individual products themselves but people continue to order them incorrectly. This causes a lot of work for me communicating with the customers and or refunding orders.

Any idea? Do I need to have a special mod written?
