Special Prices for some customers

I have asked this question before but did not get far as it is probably too hard with the templates available.

I want a website open to all customers and I have a basic price (A) for these purchases. Certain customers belong to a group which is allowed to buy the same products at another, lower price (B).

The difference in the price is not a FIXED $ amount and it is not a FIXED % amount however on all products added to the website, I have put in a Price A and also a Price B.

How can I EASILY flag the special group of customers so that when they log in they automatically are seeing the lower price?

Don_in_OZ :confused:

put in all customers with special prices into the user-group for this special price (A,B or C)

I think he is looking for a solution like: UsergroupX = PriceA and UnsergroupZ = PriceB etc.

customers can be part of more than one usergroup, so just assign additional the group price a, b or c

But this must be assigned manually - who else than you knows, if and when the single customer gets a special price.
