Get collect on delivery to work with paypal etc.

Hi

Ive been trying to adjust hikashop to confirm orders for FREE items. My latest experiement was to:

create a new delivery method of "FREE items" which is linked to "Payment on delivery".

"FREE items" delvery method is only valid if your has a maximum cart value is 0.01. Which I figured is the same as FREE.

This doesnt seem to work. Have attached screenshots of the delivery method and payment settings.

Is there something Ive not done to make this work? Every item has a cost assigned to it. The FREE items have 0.0 as cost.

Hi Ive just turned that on, paid items going through to paypal fine but free items going to:
warrenmiller.co.uk/nationwidetickets/checkout/step/step-1 and coming back with the 500 error

Re the option I turned on, would that mean I should assign a weight to the paid for tickets to stop their being mis identification as free tickets (collect on delivery)?

When I turn off auto select payment and delivery when there is only one option it seems that no payment or delivery options are deemed suitable for this transaction (their not appearing) despite the free tickets being the only item on the shop which is free :/ (below the maximum cost of 0.01). Shouldnt free items match with the setup shown?

I just checked the "free item only payment option" is matching with baskets with any basket except ones which consist solely of FREE items :/ Have to turn it off for now as the shop is live. Cant think how else I can differentiate products I thought setting the delivery / payment option to only trigger with items under 0.01 would equal all free items?
