Updates to Big Chooser for Zen Cart

(12/2012) Most people, when doing an item-count based discount, just want the least expensive item to be discounted. This kind of discount - "Buy 3, get a 4th item free" can be done with Zen Cart Big Chooser. But sometimes people want to specify a particular item: "Buy 3, get product 768 free." This will work as long as product 768 is less expensive than the other 3 items in the cart - because Big Chooser selects items to meet the condition from most expensive to least expensive, and selects items to be discounted from least expensive to most expensive.

One customer had a high-priced item that was old stock that they wanted to clear out, so Big Chooser changes were required. So to allow I modified the behavior of set_negative_constraint in Big Chooser to make it work the way Big Spender does - simply eliminating the item from the decision about whether or not the constraint is met, but keeping it as a possibly discountable item. So you can say
   $this->add_condition("Buy any 3 items, get item 768 free", false); 
      $this->set_constraint(MINPRICE, 0.01, 3);
      $this->set_negative_constraint(PROD, 768);
      $this->set_discount(PROD, 768, 1, "%", 100);
and product 768 will be discounted even if it's the most expensive item in the cart.

Sale Ending/Special Ending on Centerboxes is only $20.

Updates to Zen Cart Big Chooser for Attribute Based Discounts

(10/2012) A bug was discovered which affects the creation of attribute based discounts in Zen Cart using Zen Cart Big Chooser. Thanks to Doc Mile fine paper store for the bug report and helping me track it down. Big Chooser 1.2.15 fixes this issue.

Re-sorting Discount Modules for Zen Cart

(10/2012) Users wishing to sort native discounts (such as Coupons or Group Discounts) after my Zen Cart discounts, with tax recalculation, should look at this page. (An example of this would be doing a Big Chooser discount, then applying a percent off coupon.)

Coupon Auto Add for Zen Cart

(10/2012) I have created a new mod which automatically adds a specified item to the cart when a specified coupon code is entered. It's called Coupon Auto Add. It works with Zen Cart 1.3.9 and 1.5.x.

BOGO Discounts across the whole cart for Zen Cart

(09/2012) A surprising number of people have asked for Buy One Get One Free or Buy Two Get One Free style discounts for all products in their cart (either for the same product or for products of lesser or equal value). You can do this with Big Chooser (see examples 7 and 8 in Advanced Configuration of That Software Guy's Zen Cart Discount Modules), but it requires writing a specific customization that makes it hard to easily switch to a different policy (say, Buy One, Get One half off) the next month. So I created BOGO Discount for Zen Cart, a module that lets you easily create "Buy some-number-of-X, get some-number-of X at a reduced price" style discounts - for identical items, items in the same category, or items without restriction.

And yes, Discount Preview supports BOGO Discount too!

Updates to using Coupons with Zen Cart Big Spender and Big Chooser

(08/2012) I had not updated the Zen Cart Coupon Extensions Help Page in a number of years; I just updated the changes required to 1.3.9 and 1.5.0 to make my coupon tricks work. This allows you to offer a complex discount (such as can be done with Zen Cart Big Spender or Zen Cart Big Chooser) but also make the discount dependent on a coupon code.

Updates to EZ-Pages Meta Tag Fields Contribution

(08/2012) The EZ-Pages Meta Tag Fields contribution has been updated to support Zen Cart 1.3.9.
