Reply To: Buy 4 Get 1 Free

[Soft79]

I think you didn’t really understand my last post. The plugin will discount every cheapest item in every group of 4 items sorted expensive to cheap. Let me give an example:

Imagine this cart:

• Product A: $ 100
• Product B: $ 100
• Product C: $ 100
• Product D: $ 99
• Discount: – $ 99
• Total: $ 300

The discount is $99, no problem so far. Let’s imagine the customer now adds a $ 5 product. This is how the plugin would apply the discount:

• Product A: $ 100
• Product B: $ 100
• Product C: $ 100
• Product D: $ 99
• Product E: $ 5
• Discount: – $ 99
• Total: $ 305

Our plugin still discounts $ 99. In your case the discount would change to $ 5, like this:

• Product A: $ 100
• Product B: $ 100
• Product C: $ 100
• Product D: $ 99
• Product E: $ 5
• Discount: – $ 5
• Total: $ 399

So just by adding a $ 5 product, the cart total would increase by $ 99. That’s not fair!

Another example. Please see the cart from your screenshot. You want a discount of $ 39 + $ 39, right? But in that case the customer would be better off if he’d place two separate orders like this:

Order 1:

• $ 390, Vitamin D3
• $ 390, Vitamin D3
• $ 390, Vitamin D3
• $ 170, Vitamin B50
• Discount: – $ 170

Order 2:

• $ 170, Vitamin B50
• $ 139, Biotin
• $ 39, Vitamin C
• $ 39, Vitamin C
• Discount: – $ 39

You see?
