Okay ... much better! There is now a group-specific pricing field in my "product edit / new product" window.

Incidentally, READ ME file for the plugin should be changed to show name change in the following files (directory path):

STORE/admin/includes/extra_datafiles/group_price_per_item.php
STORE/includes/languages/english/extra_definitions/group_price_per_item.php

Currently it locates the includes "group_price_per_item.php" file here in 1.5.5 (which is not in the 1.5.5 zip pack):
* /includes/extra_datafiles/group_price_per_item.php



Last two questions re this plugin:

1) We use the term "member" and "non-member." Is there a way to change the discount verbiage to use those terms rather than "starting at" and "retail" for prices? (In fact, can I get rid of "starting at" completely since the prices are flat rates, not sliding scale)? We are a non-profit org so "retail" doesn't make sense for our products.

2) Is there a way to accommodate various multiple purchases? ie, in one case the customer is offered 3 items for $45 for members, and 3 items for $48 for non-members. I thought initially of different groups (multiple purchase non-member and multiple purchase member) but the volume discount is different for different numbers (sometimes 3, sometimes 10, etc.) and my boss doesn't want to deal with too many groups.

THANK you!
