The Buy X Items - Get 1 Free module gives the shopper a discount based on a predetermined qualifying number of items. In the admin module, the store owner sets the number of items it requires in order for the lowest priced item to be free.
Use the Merchant admin upload feature to upload the module. Once uploaded, click the Add button to add it to the mall/domain.
In admin, under your store, click on the link for Utilities Configuration Screen. Assign the module and Update it to install it in your store.
Click the link for Buy X Number Items Get 1 Free to enter the configuration setting.
Enter data into the applicable input field.
Quantity
For every increment of the number entered, an item's value reduces the total
sale. For example, if the number is 5 and the customer buys 5, the lowest
priced item is free. If the customer buys 10, the lowest priced two items
are free.
If you are using the Miva Merchant User Interface (mmui) you will need to make some very simple edits to the core files. Be sure to do that with a text editor (NO WYSIWYG editors) such as Programmer's File Editor (PFE) so as not to damage the mv files. ALWAYS BACKUP your unmodified mv files in case you make a mistake.
In the mmui.mv file MMUI_DisplayBasket function there are two areas where you will insert code.
1) Insert the following line as the first line after the beginning of
the MMUI_DisplayBasket function.
<MvDO FILE = "{g.Module_Root$'modules/util/get1free.mv'}" NAME = "l.freeitemtotal" VALUE = "{FreeItem_Insert()}">
2) A few lines before the end of this MMUI_DisplayBasket function you
will see a table row which contains the Total: for the basket. Add the
following just before the <TR> tag:
<MvDO FILE="{g.Module_Root$'modules/util/get1free.mv'}" NAME="g.discountbasket" VALUE="{Display_FreeBasket(l.editable)}">
