Recalculating Free Shipping after a discount in Zen Cart

Periodically, the question is asked on the Zen Cart forum, “how can I set the Zen Cart Free Shipping threshold based on the Total AFTER all discounts and coupons have been applied?”

This can be done but there are a lot of variables involved.  (If it was a simple mod, I’d package it up as a simple mod!)  So I offer it as a service.  It’s called Free Shipping Recalculation.  It recomputes your free shipping threshold based on the subtotal after discounts.

Free Shipping Recalculation works, whether you are using Admin->Modules->Shipping->Free Shipping Options or Admin->Modules->Order Totals>Shipping to set your free shipping threshold.

Better Together Admin now 50% off

Now that Discount Chooser is becoming the gold standard for discounting offers in ZenCart, osCommerce, and (soon) OpenCart, I have decided to reduce the price of Better Together Admin.Better Together Admin for Zen Cart and Better Together Admin for osCommerce are now price reduced to just $30 for software only, or $90 for the software plus installation. If you have been holding off on buying the Better Together Admin Panel, now is your chance.

If your discounting needs are limited to BOGO style offers, Better Together is still a great choice, so I hope a lot of people will take advantage of this lower price.

Welcome, Discount Chooser and Discount Spender!

When I first created Free Gift Chooser, it only offered 100% discounts (“free gifts”), based on the content of the cart. About a year later, I added the ability to do price reductions – percentage or dollar based. So the name “Free Gift Chooser” was no longer very accurate.

With the pending release of the Free Gift Chooser algorithm for OpenCart, I’m taking this opportunity to rename the Zen Cart and osCommerce versions of Free Gift Chooser to Discount Chooser (and similarly, to rename Free Gift Spender for Zen Cart to Discount Spender).

Same powerful discounting software; new name!

Better Together for Zen Cart Updates

Back in 2013 I extended the one-to-one linkage concept in Zen Cart Better Together with the One-to-Many feature.  This addition of three new radio buttons in the Zen Cart admin panel effectively tripled the number of permutations of computed discounts.  What could go wrong?

Well, as it turned out, a number of things!  Freed from the classic one-to-one constraint, the configuration

add_prod_to_prod(3,3)

would discount a *single* product 3, because it miscounted the number of items in the cart.  You can see this error in the screenshot above.

This bug is fixed in Better Together 2.5.3 for Zen Cart, which is available in the Plugins area.

2 series Mastercards and your Zen Cart

You may have already heard that Mastercard is rolling out cards that start with a “2” instead of the traditional “5.”  You’ll want to check your version of Zen Cart to be sure you can handle this.  Versions 1.5.5b and above have built in logic for the native payment methods (such as Authorize.net); if you are running a lower version, you will need to merge in the changes from the latest copy of includes/classes/cc_validation.php.  If you are using an extension to manage credit card payments, be sure to test with Mastercard 2223000048400011.  Then you can have confidence that your cart properly processes “2” series Mastercard cards.
