This catalog now holds two dated readings rather than one, and the honest answer is that nothing in it went on sale between them: the Keychron V5 Max at $109.99 (keychron.com) was identical to the cent on 2026-08-26 and 2026-09-06, and so were the Keychron K2 Pro at $74.99, the K3 Pro at $67.99 and the C3 Pro at $34.99. The one board here whose US-dollar price moved between the checks moved up: the Keychron Q1 Pro reached $167.99 on 2026-09-06, and was out of stock at keychron.com on that date. What a discount looks like in this catalog is end-of-life clearance rather than a seasonal cycle — the Glorious GMMK Pro's 2026-08-26 listing carried a compare-at price making it a roughly 29% markdown, alongside an 'EOL' tag, and the Glorious GMMK 3 is tagged EOL too — but both were out of stock at gloriousgaming.com on both checks, and both 2026-09-06 readings are Canadian-dollar figures (CA$159.99 and CA$169.99) that cannot be compared to the 2026-08-26 US-dollar ones. The cautionary end-state is the Epomaker TH80 Pro: its $99.99 figure is a historical launch MSRP, not a current price at all — the product is fully delisted from epomaker.com and its own product page returns a 404. Caveats: two dated snapshots are not a price history, so no calendar pattern can be read from them; every figure is a maker's own listing read on the date given; and prices and stock change without notice.
The limits first: this catalog holds two dated snapshots per product, not a tracked price history, so no calendar pattern can be read from it, and every figure below is a maker's own listing read on the date given. The four Keychron boards with a first-party US-dollar price on both dates — the V5 Max at $109.99, the K2 Pro at $74.99, the K3 Pro at $67.99 and the C3 Pro at $34.99 — did not move by a cent between them, which is the whole of this catalog's evidence about seasonal discounting. The GMMK Pro's discount was explicit and traceable on 2026-08-26: the manufacturer's own product feed carried a compare_at_price against the then-current US-dollar figure, a roughly 29% markdown, alongside an EOL tag and a 'Sale_BDAY' tag. It is no longer checkable in the same units — the 2026-09-06 re-check recorded CA$159.99 at the same store, a Canadian-dollar reading. And that price applies to a barebones board — no switches, no keycaps included, so a buyer still budgets for both on top of the sale price — and all four variants (Black Slate and White Ice, in ANSI and ISO) were out of stock at gloriousgaming.com on both the 2026-08-26 and 2026-09-06 checks. A clearance price on a board nobody can currently order is not the same thing as a sale you can act on.
The GMMK 3 tells a more layered version of the same story. Its own product feed also carries an EOL tag, and the base 65% Black English(US) SKU — the specific configuration priced here, at CA$169.99 on the 2026-09-06 re-check — was out of stock on both check dates. But the same listing's 75% and 100% English(US) variants (Black and White 75%, Black 100%) were in stock at the 2026-08-26 check. So 'end of life' here doesn't mean the whole product line vanished at once; it can mean one configuration sells through and stops while siblings in the same SKU family are still fully available. QMK is not supported on this model per the manufacturer's own spec table, worth knowing regardless of price.
The Epomaker TH80 Pro shows where that road ends. Its $99.99 figure is not a current price signal of any kind — it's the historical launch/list MSRP as reported in contemporary reviews (Soundphile Review; a Tom's Guide headline calling it 'the $99 thock'), re-attributed here only after confirming epomaker.com no longer lists the product at any price. The board is absent from Epomaker's own product feed across all 130 listed products, and its product page returns HTTP 404. There is no first-party price or stock signal for it at all, sale or otherwise; it has been superseded by the TH80 V2 Pro and TH80 V2, which are Epomaker's current listings in that slot.
This isn't a pattern to plan a purchase around if what someone wants is a guaranteed-stock board with full ongoing support — an EOL tag correlates with reduced stock in two of these three cases, and with total delisting in the third. It's also not the right frame for a first-time buyer who needs a board they can type on immediately: the GMMK Pro's clearance price is for a barebones unit requiring separate switches and keycaps, on top of being out of stock. Anyone who wants the closest in-stock equivalent to the Epomaker board should look at the TH80 V2 Pro or TH80 V2 directly rather than the delisted TH80 Pro; anyone who wants a GMMK 3 today should look at its 75% or 100% variants, which were in stock even while the 65% base SKU was not.
