전국핫딜 (jkhotdeal)
A deal site and app that records Coupang prices and shows whether today's price is lower than usual. The usual price is the median of the last 90 days of records; when records are too few or the product mix changes, no verdict is given.
For bundles, it reads the quantity and size from the product name and also shows the price per item or per 100 g.

Key features
Today's deals
Items recorded at least 5 times over more than 14 days that are at least 5% below their usual price, sorted by the size of the drop.
Price records and verdicts
Each item shows its price, usual price, record period and count, with verdicts such as 'lowest in our records'.
Unit prices
Bundles get a per-item or per-100 g price. If the quantity cannot be read, it is left blank.
Search and categories
Search recorded items, or browse food, household, beauty, fashion and digital.
App
