If something here is wrong, [tell us and it goes in the log](https://mkelango.com/evidence/). ### What can you buy on mkelango.com? Three categories. The six books of the Elango Stack, individually or as the ₹4,800 boxed set; six printed instruments — the Coherence Matrix pad, the Ladder canvas, the 12-Traits assessment pad, the Mission card deck, the Flywheel wheel and the CCi tear-down sheet, ₹1,200 to ₹3,200; and five digital items, from the AQ Deep Report at ₹4,900 to the AI Flywheel 90-Day Start self-paced at ₹12,000. ### Does the shop sell merchandise? No. There are no supplements, no apparel and no branded water bottles. Every item is either a book, a printed instrument that gets written on, or a digital report you run against a problem. The printed instruments exist because a matrix filled in by hand at a board table is treated differently from one on a screen. ### Can I buy anything on the site today? Not yet. Payments are not connected as at 26 August 2026 — Razorpay for domestic and Stripe for international both need wiring, along with ISBNs on the retail links and a published shipping rate card for the printed instruments. The prices shown are the intended bands, and the page says so rather than failing at a checkout. ### If I buy a digital report, does the free diagnostic stay free? Yes, permanently. All six diagnostics, the score, the benchmark, the method and the band reading remain free, with no email gate. The paid report is more — the trait-by-trait breakdown, the full benchmark set with sources and dates, and the moves that shift the score fastest. It is never the same thing placed behind a wall.
