Force shipped for for a cart with a 0 total (free)

[enricocerica]

Hi,

I would like to know how I can automatically set the status to shipped when a shopper checks out a cart with a total = 0 which means that he selected free products (price=0).
Once he checked out and confirmed the purchase, he got a message saying that the order has been processed but the status remains to pending.

Any idea ?
Thanks

guess it would need some sort of custom plugin written
