Quantity Discount

[nextprevious]

I have a cart with less than 20 items, most of them are $35 but one or two are $2.50.

 

I need to setup a discount based on the quantity of products in the cart. This would only have to apply to the $35 items, and not the other items.

 

 

Example:

cart has two watches at $35 each and two belts at $35 each

the discount would be 15% off 4 of the $35 items

 

Example:

cart has six $35 items (different products, mix-and-match) and two $2.50 items.

the discount would be 20% off the six $35 items.

 

I need it for multiple tier quantity discounts, eg. buy 4 save 15%, buy 6 save 20%, buy 10 save 30% etc...

 

Im thinking this:

 

Quantity Discounts

A drop in quantity discount module. It allows you to specify the discount percentage based on the number of items bought. This is not products_id based and is site-wide. Any combination of items will work as it runs of the total number of items in the cart.

 

If I could apply this addon only to a group of products, say products priced $30-$40.

 

Thank you.

Okay so i installed the Quantity discount contrib and it works great.

 

I dont need the discount to apply only to a group of products.

 

Is there some way I could calculate and show the discount in the shopping cart?
