Every retained reading

Verified at checkout at Growth Guys (growthguys.com) on November 10, 2026 at 4:47 a.m. ET: HEALTHYLIFE10 applied 10% off sitewide with no product exclusions, no minimum purchase, and it works on all orders including the highest-priced items, taking a $50.00 CAD cart to $45.00 CAD — a $5.00 CAD reduction and the table below is every other reading taken since this record opened, newest first, passes and failures alike.

365 readings on 73 days, across 87 products, carts from $40.00 CAD to $1,800.00 CAD, $4,520.99 CAD of observed reduction in total. Each date links to that day's carts in full.

A row is only added once its reading is complete, and no row is edited afterwards. Where a day carries several carts the table totals them; the day's own page keeps them separate with the time each was taken.

What the series establishes

Across all 365 readings the discount line returned the same figure every time: exactly 10% of the cart subtotal. Not a mean of 10% and not a range around it — 365 readings, one value, no spread. That is the single fact this series exists to establish, and it is the one a reader cannot take on trust from anybody, including us, without a dated record behind it.

The readings are spread across 87 different items rather than repeated against one convenient product, and across carts from $40.00 CAD to $1,800.00 CAD with a median of $75.00 CAD. A code that only holds on small carts, or only on one category, would show up as a gap in that spread. $4,520.99 CAD of reduction has been observed in total.

Readings by item

When the readings were taken

The 365 readings fall on 73 separate days within a 73-day window, at clock times between 00:00 and 23:00 — the spread of a job that runs on a schedule rather than one that is triggered when the answer is likely to be convenient. Times are recorded to the minute on each day's own page. Where a day is absent from the table above, no reading completed that day; the gap is left visible rather than interpolated.

Repeating a reading

Nothing here needs to be taken on faith. Open growthguys.com signed out, put any item in the cart, enter the code at the cart stage, and read the discount line against the subtotal shown beside it. The figure on this page is that line, recorded. A reading stops there — the cart is cleared, no address is entered and no order is placed — which is why every row above is an observation of a cart and not of a purchase. The machine-readable form of each day sits beside its page as JSON.

What this series does not establish

It is a record of one thing. It shows what the discount line returned on the dates listed. It does not speak to what any order did after checkout, to how quickly anything shipped, to what arrived, or to how the vendor handled a problem. Those are separate questions and a cart reading is not evidence about them. A reading is also only true of the moment it was taken: the rows carry their dates because a code can be changed by the vendor at any time, and the newest row is the only one making a claim about today.
