I've been searching around the zen cart pages and the forum looking for a group pricing mod that would:
* allow more than four different groups
* Allow prices to be set per product for each group (1 - N groups)
* Allow for setting prices, not % - discounts ( group discount module) and again, per item

Does this exist?

Another (ugly hack ) solution to my problem would be to limit the visibility of products per user group. Then I could add the same product many times with different prices and set the visibility only to the groups I wanted... Possible?

Example:
Product A has a base price of $10,
product B has a base price of $20

Users in Group X gets product A for $8, product B for $19
Users in Group Y gets product A for $7, product B for $20 (normal price)
Users in Group Z gets product A for $6, product B for $12
and so on..

Cheers
