Checkout extensions that are worth the milliseconds
The platform caps most of the damage an extension can do. What is left is network calls, stacked extensions and rules built in the wrong layer.
The checkout you cannot change, and the one you can
Checkout is now three narrow, well-documented surfaces instead of a template you could edit. Knowing which of the three a request falls into answers most of the scoping.
Reading the Summer Edition like an engineer
The Edition is the announcement. The changelog and the API version schedule are the documents that actually bind you, and only one of the three has a deadline in it.
Gift with purchase, tiered discounts and cart-level promotions
The discount system reduces prices. It does not put things in carts. Once you know which half of the problem you are solving, the build stops being a fight.
Custom checkout logic with Functions: three worked examples
Functions run inside Shopify’s own checkout, which is why they can do things no script in your theme can — and why they cannot look at a clock.
Checkout branding: how far Shopify lets you go now
The Checkout Branding API goes further than most teams realise, and most teams should still stop after the first four changes.
A year of Shopify: what mattered and what did not
Two Editions and a year of changelog entries. Five changes altered a decision worth money; most of the rest were a press release with an illustration.

The Edition lands in the new year. The useful preparation is a place to test things, not a list of things to adopt.

Discount logic that survives your next promotion
Shopify Functions will express almost any discount rule you can describe. The limits that break a promotion are the boring ones: how many discounts can be active, and which of them combine.
