Have a look at Checkout Candy for Zen Cart and see the how you can promote your Zen Cart store’s cross-sells!

Running Edit Orders or Super Edit against an order with one of these discounts will improperly change the minus sign in the discount amount to a plus sign.  So a Better Together discount of $15.00 will become a $15.00 surcharge.

The root cause of this bug is that both of these mods, when updating an order, enumerate through a fixed list of classes to see if the order total in question a known native discount (coupons or group discounts), and otherwise, assumes it’s a surcharge.

The fix is to modify admin/edit_orders.php and admin/super_edit.php as follows:  search for

 $ot_class == "ot_coupon"

and add in the classes you are using.   For Better Together, this would be

$ot_class == "ot_coupon" || $ot_class == "ot_better_together"

For Better Together and Quantity Discounts, this would be

$ot_class == "ot_coupon" || $ot_class == "ot_better_together" || $ot_class == "ot_quantity_discount"

“if statements” containing this check occur several times (depending on version) in the two files; make sure you get them all.

A complete list of the classes I have created that require this fix is:

• Better Together: “ot_better_together”
• Big Chooser: “ot_big_chooser”
• Big Spender: “ot_bigspender_discount”
• Combination Discounts: “ot_combination_discounts”
• Frequency Discounts: “ot_frequency_discount”
• Quantity Discounts:  “ot_quantity_discount”
• Newsletter Discounts: “ot_newsletter_discount”
• Military Discount: “ot_military_discount”

If you want a complete if clause that handles all of these plus the built in discounts (including GV), it would look like this:

if ($ot_class == "ot_gv" || $ot_class == "ot_coupon" || $ot_class == "ot_group_pricing" ||
                 $ot_class == "ot_better_together" ||
                 $ot_class == "ot_big_chooser" ||
                 $ot_class == "ot_bigspender_discount" ||
                 $ot_class == "ot_combination_discounts" ||
                 $ot_class == "ot_frequency_discount" ||
                 $ot_class == "ot_quantity_discount" ||
                 $ot_class == "ot_newsletter_discount" ||
                 $ot_class == "ot_military_discount"
) {

Big Spender is dollar based discounting. Spend over a certain dollar amount, get a discount on other products / receive other products free.

These extensions are based on algorithms of the same name for Zen Cart which have been around for a while, so osCommerce users get the benefit of field-hardened code from day one.  Big Chooser and Big Spender are ready for deployment to your osCommerce based cart today!
