0.3.0 Foxycart has the option to pre-populate the data for the checkout.
However, to by pass the password requirement one of the fields needs to have a %20 in it.
I'm using all the fields, so I don't have one to make it blank...
Ah, I think I see the answer: you can add any field to the link with %20 in it to create the over-ride.
Is this the case?
