This is not the easiest MOD to explain, but this is basically how it works ....
CUSTOMER:
You set a customer to be Retail or Wholesale.
If Wholesale, you set a Pricing Level for that customer.
When a customer logs in, they see all products shown with their price level.
PRODUCTS:
You set as many price levels for an item as required.
Price levels should go from Highest Price to Lowest price.
i.e.:
Level 0 - is Retail,
Level 1 should be the next price down
Level 2, the next and so on ...
L0: $10
L1: $9
L2: $8
L3: $7 ..... and so on
What happens is, if a wholesale customer, L3, looks at a product that
say only has level 0 & 1 set, the Mod will walk backwards from L3 until it finds a Valid Price.
This allows you to only set lower levels on the products that need it.
One other feature is that you can set an entire category to a specific customer.
No-one else will ever see that category and the customer will only see it when they
login to their account.
All products show RETAIL until a customer logs in. After login, they will see prices
relevant to their Price Level
