How long the markdown has stood

Of the 31 items reduced today that have at least 14 days of recorded prices, 31 carried the reduction on 80% or more of those days (our price history starts 2026-07-19). For most of them that is a standing "was" price rather than a sale, so waiting for a deeper one has no basis in this store's own history.

Was the “was” price ever charged?

Of the 23 items marked down today with at least 30 days of recorded prices, 23 never carried their “was” price as the selling price on any of those days. How this is measured →

Questions

Does COSRX have a discount code right now?
We do not host coupon codes. What we can show is what COSRX itself marks as reduced: 31 products carry a compare-at price above their selling price, a median of 14% below it. Most of those markdowns are not new: 31 of the 31 items reduced today with at least 14 days of recorded prices carried the reduction on 80% or more of those days, which is a standing "was" price rather than a sale.
How much is COSRX discounting?
Median 14% off across the 31 reduced products, deepest 19%. 20% of the products we hold for this store are reduced.
Are COSRX's discounts real?
Of the 23 items marked down today with at least 30 days of recorded prices, 23 never carried their "was" price as the selling price on any of those days. A "was" price is meant to be one the item actually sold at; this is our own daily price record, not a legal finding about the store.
