Quantity Discounts for 1.3

[Ajeh]

I add 5 and get the discount ...

In the cart I see:

5 $135.00 $675.00

In the checkout_payment I see:

Sub-Total: $675.00
Free Shipping Options (Free Shipping): $0.00
13% HST: $87.75
Total: $762.75

In the checkout_confirmation I see:

Sub-Total: $675.00
Free Shipping Options (Free Shipping): $0.00
13% HST: $87.75
Total: $762.75

What were you wanting to see?

You are using the native Quantity Discount in Zen Cart, not the Quantity Discount contribution. In the native Quantity Discount, the price is reduced in the cart. If you add 2 boxes of checks (the link you gave), you'll see the price is $165 rather than $175. So no discount is displayed as a line item; that's how the native Quantity Discount works.

Thanks everyone! the problem was that the item was set to be priced by attributes and therefore didn't calculate the discount.

I did however install the contribution but couldn't figure setting the discount to a specific item.

The Quantity Discounts contribution is not designed to apply a discount to a single item; it's designed to apply a discount to all items. If you want a quantity discount on a single item, you should use the built-in facility for doing this.

I have an issue with quantity discounts and group discounts. I want to subtract the quantity discount from the order subtotal, compute the group discount on the result and subtract it from the subtotal. Then I want to add the shipping cost and compute tax on the result. When the tax is zero, everything is calculated properly, but when the tax is non-zero, the amount used to compute the group discount is wrong. It is too low by an amount equal to the tax on the quantity discount. The quantity discount amount itself is correct. I have the include tax control set to false and the recalculate tax control set to Standard for both quantity discount and group discount. Quantity discounts has a lower sort order than group discounts.

If I set the quantity discount control for tax recalculate to None, the quantity discount amount and group discount amounts are correct but the tax on the order is wrong, being too high. Any suggestions for setting the controls or is this a bug?

I'm using Zen Cart 1.5.1. Thanks in advance!

Hello. This is probably a really stupid and basic question. And I have read the documentation and...well and least some of the posts. I have 2 products of Jeans. Jeans A and Jeans B. both are RRP $59.95. I want to be able to provide a discount of $9.95 if the customer buys four of either Jeans A or Jeans B or a combination of both eg: 2 of Jeans A and 2 of Jeans B. Is this Mod capable of doing this- I understood it could? I have installed the module no problems. But for the life of me cannot work out how to apply the module to these products!? Surely the discount does not apply to every product in the store.?

Actually, the discount *does* apply to every item in the store. :)

If you downloaded Quantity Discounts in the last 3 weeks, please make this small change to ./includes/modules/order_total/ot_quantity_discount.php - at the bottom of the file in the function setup() change

       $this->add_extra_level_discount(500, 55);

to

      // $this->add_extra_level_discount(500, 55);

i.e. comment the line out - this was only intended as example code. Thanks to Tim Lester for spotting this.
