Swapped a tiered pricing plugin for two coupons

phpnerd

Tried to use this technique - https://developer.woocommerce.com/2026/07/01/auto-apply-coupons/ - to replace an existing tiered pricing plugin on an existing client site

Two core coupons plus some PHP - the PHP sets the correct one when cart quantity passes a threshold - all in all about 60 lines of PHP code.

We have also removed the plugin and checkout is measurably faster on staging if you can believe that. Also no longer need yearly license...

The rest will be in the same PHP code, just adding some logging.

How does it apply without a code?

Ok, we calculate this on cart totals and compare the number of items in the cart to the thresholds and apply a matching coupon (or remove an old one).

All done server-side: no coupling to coupon fields anywhere.

We had a customer asking about the 'discount at checkout' line in their shopping basket.

This would be better explained and reduce customer support calls, by using a tiered-pricing plugin and then being able to show the lower unit price directly on the product page (and which performs better as well)

Fair point but I achieved this using a fairly small pricing table in the product description which I need to do manually.

The plugin rather did it for me...

Does this work for the Block based checkout as well or only on the standard short code based checkout?

phpnerd

This works fine in the block based checkout (tested this after upgrading to WooCommerce 10.9.4) - the coupon shows in the order summary and gives the right total.

Hope this helps!

One last thing:

Now I use coupon usage as an (indirect, but real-world) way to track which pricing tiers are hit at what frequency, which is a neat data set. And since I never did track or report tier hits, it wasn't possible with the plugin.

Just thinking aloud, since this is pretty unique.

We did the same for a free-shipping threshold, just using a single coupon and no snippet at all. It works, but you lose the reporting, you cannot see how often the threshold is hit.
