Our price tracking, and what it currently shows
mid1 takes and stores its own weekly price snapshot. The weekly series starts on 2026-06-24 and holds 481 dated observations across 140 products, a median of 2 checks per product over 14 days. As of 2026-09-14, 1 products sit below every other price on our record for them, and 2 are below the median of their own recorded prices. A further 1 monthly points on 1 products, all dated before 2026-06-24, were bought from a commercial price-history API rather than checked by us, and are marked as backfill wherever they appear.

The Typical-Price Test
A discount only counts as a real sale on mid1 when the current price is below the median of our own tracked price snapshots, not when it is below the manufacturer list price.
List price is close to meaningless on most marketplace listings: items sit permanently at "20% off" a number nobody ever paid. We compare against the median of the prices we have actually recorded for that product, so a sale badge means the thing is genuinely cheaper than it usually is. Where Amazon shows its own strikethrough we display that figure attributed to Amazon, and it never becomes the typical price. A tracked low needs the price to have moved: we flag one only when we have recorded at least three different prices for that product and the current price is below every other price on our record, so a price that has never changed is never called a low.
The full set of rules is on the methodology page.
At a tracked low right now
Products whose current price is below every other price on our record for them. A product needs at least three different prices on record to qualify, so a price that has never moved is never listed here. 1 of 140 qualify as of 2026-09-14; the first 1 are shown.
| Product | Price, and when observed | Previous low | Checks taken |
|---|---|---|---|
| Korg nanoKONTROL2 Slim-Line USB Control Surface | $70.11 on 2026-09-14 | $70.27 (2026-08-31) | 4 |
Furthest below their typical price
Measured against the median of our own snapshots. Amazon list prices are excluded from this calculation entirely: a discount off a number we never observed is not a discount. 2 products are below their own median; the 2 furthest below are shown.
| Product | Price, and when observed | Median of our record | Below median |
|---|---|---|---|
| Professional Audio Mixer | $116.99 on 2026-09-14 | $129.99 | 10% |
| Arturia KeyLab mk3 USB MIDI Keyboard Controller | $431.10 on 2026-09-14 | $479.00 | 10% |
Citing this data

Common questions
Where does mid1 price data come from?
mid1 runs its own price snapshot once a week and stores the result, so every price on the site carries the date it was observed. The snapshots are stored with the site as data rather than fetched from a third party when a page loads, so the history survives even if an upstream source disappears.
How does mid1 decide something is on sale?
A discount only counts as a real sale on mid1 when the current price is below the median of our own tracked price snapshots, not when it is below the manufacturer list price. List price is close to meaningless on most marketplace listings: items sit permanently at "20% off" a number nobody ever paid. We compare against the median of the prices we have actually recorded for that product, so a sale badge means the thing is genuinely cheaper than it usually is. Where Amazon shows its own strikethrough we display that figure attributed to Amazon, and it never becomes the typical price. A tracked low needs the price to have moved: we flag one only when we have recorded at least three different prices for that product and the current price is below every other price on our record, so a price that has never changed is never called a low.
Can I cite or reuse this price data?
Yes. The mid1 price-history dataset is available for reuse under the Creative Commons Attribution 4.0 licence, with attribution to mid1 (mid1.com) and a link to the page the figure came from.
How current are the prices on the site?
Every price shown on mid1 is a dated observation, not a live quote, and it is displayed with the date it was taken. The most recent weekly run was 2026-09-14. An observation that falls more than ten days behind the latest run loses its sale and tracked-low badges until it is checked again. The retailer link on each page always carries the current price.
How far back does mid1 price history go?
Our own weekly series starts on 2026-06-24, so the median product carries 2 checks over 14 days. 1 products additionally carry monthly points dated before 2026-06-24; those were bought from a commercial price-history API rather than taken by us, and they are labelled as backfill on the product page. We do not claim years of first-party history that we do not hold.
