AUSTPost module

[RodG]

I am wondering, however, if it is possible to forcefully exclude certain items in a bulk order from group packaging/shipping, where an item is always shipped in its own packaging and at its own shipping rate.

With zencart anything is possible. :-)

I am thinking specifically of poster tubes that cannot (or should not) be included in normal boxed or bagged packages, however, there may be other items of similar circumstance.

I imagine a simple checkbox would be solve this problem, but I have no real understanding of how to construct or implement same.

Your thoughts or solutions greatly appreciated.

TIA

A 'simple checkbox' would only be the icing on the cake. Additional code will be required to make the checkbox actually do something. :-)

Anyway, if you are looking for an 'easy' solution, there isn't one. Probably the best way to achieve this would to create a special category for the items in question, and then modify the austpost.php code to exclude that category from normal processing. The means of doing this has been discussed in other threads/posts.

Needless to say, if the items are excluded from the normal processing you will then need to add an alternative postage method (or pricing) to handle their charges.

Cheers
