What it costs

No cost figure is published for Gift Cards, because none has been measured.

Gift Cards cannot be installed on OpenCart 4.1.0.3, which is the release the cost rig builds for every extension at once. OpenCart removed the voucher subsystem in 4.1.0.0 — the model, the four tables and the checkout box are all gone — so Gift Cards refuses to install there, and a measurement taken on that store would be a measurement of a store it was never on. It runs on the 4.0.2.x line; see which stores it runs on.

Every other extension here publishes nineteen measured rows, and this page prints none rather than nineteen zeroes: a +0 taken on a store the extension was never installed on is not a cost of nothing, it is a measurement of nothing. What Gift Cards costs a store it is actually installed on is a real number, and it is not this one.

How a cost is taken here, what a measurement does and does not cover, and why the rig pins one release for every extension at once: Added cost.
