PAHT & delivery method

Just set up a series of events which i would like to be ONLY PAH and online but realise this may not be possible because of MOS default (which is post), however

I have is associated Print at Home to the particular price type (which is ONLY used in the above events) in LTR_TNEW_DYN_SHIPPING_METHOD and

Print at Home is just NOT appearing as a delivery method online whereas Collect at Box Office and Post are appearing.   

Going round and round in circles and feel that I'm just missing something!  Hope some out there can help.
