This mod allows you to specify up to 4 extra pricing structures for your customers per item. So... if you have say wholesale, retail, partners and friends that you want different prices for, you can have this mod installed and when you enter an item into your store, it will show the breakdown where you can enter each individual price for the item!
When your customer logs in to the site (once you have applied a group to their customer ID) then the pricing they see will be that of the group you have assigned them to.
This mod comes in handy if you don't want to give "straight percentage" group discounts and want to give individual pricing per item to different groups.
For Zencart version 1.3.7
