Grouping price AND product

[bluetooth]

I have 10 markets (or groups of customers) that will have different pricing for each product, depending on which group they are in when they log in. I believe this can be accomplished by setting up my products using the highest prices, then using different discounts for each product in each of the 10 markets.
Am my correct in assuming this?
When setting up discounts for a group, does each product get a certain % discount in a group, or does the whole group get a % discount for all the products?

The second part is that these 10 markets will need to have access to different products depending on which group (or market) they are in. Some products will overlap, or be accessible in several groups (or markets), and some will need to be accessible only to a single group. Also, as stated above, the price of each product will be determined, depending on which group the product is in.
Anyone have any ideas on how I would do this using Zencart, or if it's even possible to set up pricing, and product availability into groups (or markets)?

I know this is kind of complicated, so if you need more info please let me know.
Thanks!

The built in Group Discount is based on a percentage for the whole order ...

There is an Add on that allows this to be done Per Product Per Group, but this is designed just for 4 Groups ...

You can, however, follow the pattern for the 4 Groups and extend this to be for additional Groups ...

Thanks Ajeh.

Any ideas as to if it's possible to the set it up as per the second part of my question?

You would need to customize the code further for that ...

Without actually installing this Add On and going through the code to see how it can be adapted to flag the Products for each Group for who can see what, it is hard to guess ...

There are a lot of SELECT statements in Zen Cart for the Products ... one of the constants would be the reference to products_status ...

Including where this is used a flag for a Group criteria on what Products can be seen would allow controlling the display of Products by Group ...

Also, keep in mind what to do when the Customer is a Guest and not logged in yet, as to how to manage what Products should display ...
