Shipping Boxes

My client wants to sell wine and other stuff. For the wine there is the base price for one bottle, but he wants to sell it either in a 6pack or 12pack box (no single bottles)
So, there is a simple calculation to be made 6-box = base-price x 6, 12-box = base-price x 12
If the client selects a quantity it relates either to the 6-box or the 12box, not the singel bottle
What would be the best set-up?
Is it a shipping rule or a product option?

Seems quite simple ... still got stuck

Use a product option.

Create a new column for CaseSize. In the add to cart behavior, set the CaseSize column to be updatable as a select list. Populate the select list with the options:
6 Bottles
12 Bottles

then create a new calculation in the eCart object calculations tab:

Name: TruesPrice
(abs([CaseSize] == '6 Bottles')?[Price] * 6:0) + (abs([CaseSize] == '12 Bottles')?[Price] * 12:0)

then edit the TotalPrice calculation to:
((abs([CaseSize] == '6 Bottles')?[Price] * 6:0) + (abs([CaseSize] == '12 Bottles')?[Price] * 12:0)) * [Quantity]

NOTE: my calculation is based on the name of the column being CaseSize and the select list values being 6 Bottles and 12 Bottles, if you use different names / values, you will need to modify the calculation accordingly.


in the cart display, change out the Price binding for the TruePrice binding, and in the code that passes the transaction to the gateway.
