Zen Cart Free Shipping Recalculation

Zen Cart Free Shipping Recalculation


Zen Cart allows you to set a dollar threshold, above which your clients will get free shipping. This is generally done in one of these two ways:
  • In Admin->Modules->Shipping->Free Shipping Options, there is a settings called "Total >=".
  • In Admin->Modules->Order Totals>Shipping, there is a setting called "Free Shipping For Orders Over".
You could also use Admin->Modules->Shipping->Table Rate and set a tier that prices shipping at $0.
This works well, except that if an order total discount is offered (coupons, group discounts, or one of my discounts). When that happens, the total price of an order can fall below your free shipping threshold, but the order will still qualify for free shipping!

However, I can change your cart to recalculate the free shipping threshold after discounts. This modification isn't a zip file you can download and install yourself; I have to make the changes for you depending on your cart files, discounts offered and configuration.

Relevance: Zen Cart™ 1.5.x

Incompatibilities: This software does not work with non-standard Zen Cart checkout flows. Please do not order this software if you use

If your business offers free shipping for orders over a certain size (either through Admin->Modules->Shipping->Free Shipping Options or through Admin->Modules->Order Totals>Shipping), but you wind up giving away free shipping to smaller orders due to discounts and coupons, this modification can help.

Coupons present a special challenge. The coupon discount is not computed until after the page starts rendering, so it's not possible to automatically throw the user back to the Checkout Shipping page. Instead, the submit button is removed, and an explanation with a link is provided.
