Coupon and shipping problems - shipping cost being calculated after coupon applied?

[shrimp-gumbo-mmmhhh]

Hello,

I have run into an issue with a coupon and shipping. The issue is that the shipping cost is being calculated after the coupon is applied.

Say an order was for 21.00 but the coupon was for $2.00

Shipping for orders over $20 is 2.00 while
shipping for orders under $20 is 4.00 .....

so the customer is paying the $2.00 shipping but should be charged the $4.00 shipping.

Here are my order_total modules:

ot_coupon 280
ot_insurance 500
ot_shipping 200
ot_subtotal 100
ot_tax 300
ot_total 999
ot_tracking 501

If I changed the ot_coupon to 99 would it bring the discount into the subtotal thus charging using the lower amount for the shipping calculation?

I discovered this issue some years ago on a site I no longer manage, and I did find a solution... I'll dig around and see if I have some notes somewhere (but don't hold your breath - I gave most of the files to the new webmaster).

Any updates on this? I am having the exact same problem.

PJB,

I tried changing the sort order of ot_coupon to be less than ot_shipping and that doesn't appear to be the fix. If anybody can help or give suggestions we would greatly appreciate it (Zen Cart team?).

Hi,
While I cannot see anything wrong initially with your settings, will test locally to see if the problem is a bug !

Just a quick update.

This is in fact a bug. In essence the table rate shipping module is using values from $_SESSION['cart'] to calculate the order value, before deciding which table rate to use.

Unfortunately the checkout system uses the $order class to calculate sub-totals/discounts etc.

I'm looking to see if there is a simple quick fix for this.

Will let u know as soon as possible

I think swguy has found a fix for it.... I think he is charging for it though.
