Though the docs on the subject have been misplaced, an "order groups" 
feature has been around since Minivend 3.  A look at Order.pm and Cart.pm 
suggests that the code is still there. Here is the doc section for Order 
Groups; good luck!

Order Groups
MiniVend allows you to group items together, making a master item and 
sub-items. This can be used to delete accessories or options when the 
master item is deleted. In its simplest form, you order just one master 
item and all subsequent items are sub-items.


     <FORM ACTION="[process-target]" METHOD=POST>
     <INPUT TYPE=hidden NAME=mv_todo ACTION=refresh>
     <INPUT TYPE=hidden NAME=mv_order_group VALUE="1">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="00-0011">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="00-0011a">
     <INPUT TYPE=submit VALUE="Order the Mona Lisa with frame">
     </FORM>

If you wish to stack more than one master item, then you must define 
mv_order_group for all items, with either a 1 value (master) or 0 value 
(sub-item). A master owns all subsequent sub-items until the next master is 
defined.


     <FORM ACTION="[process-target]" METHOD=POST>
     <INPUT TYPE=hidden NAME=mv_todo ACTION=refresh>
     <INPUT TYPE=hidden NAME=mv_order_group VALUE="1">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="00-0011">
     <INPUT TYPE=hidden NAME=mv_order_group VALUE="0">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="00-0011a">
     <INPUT TYPE=hidden NAME=mv_order_group VALUE="1">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="19-202">
     <INPUT TYPE=hidden NAME=mv_order_group VALUE="0">
     <INPUT TYPE=hidden NAME=mv_order_item VALUE="99-102">
     <INPUT TYPE=submit VALUE="Order items">
     </FORM>

When the master item 00-0011 is deleted from the basket, 00-0011a will be 
deleted as well. And when 19-202 is deleted, then 99-102 will be deleted 
from the basket.

NOTE: You cannot use checkboxes for this type of thing, for they do not 
pass a value when unchecked. Use radio groups or select/drop-down buttons.

The attributes mv_mi and mv_si are set to the group and sub-item status of 
each item. The group, contained in the attribute mv_mi, is a meaningless 
yet unique integer. All items in a group will have the same value of mv_mi. 
The attribute mv_si is set to 0 if the item is a master item, and 1 if it 
is a sub-item.
