How Dudeoji judges a price
Dudeoji Deals records the prices posted on Korean hot deal communities and store sale pages, groups them by product, and uses that record to tell whether today's price is low.
So the lowest recorded price means the lowest price Dudeoji has recorded, not the lowest price across every store. Always check the final price and stock with the seller before you buy.
Which price we record
- We record the price you actually pay: the amount at checkout without a specific card, membership or reward.
- Shipping is added. Card and member-only prices are shown separately on the deal card.
- Deals from overseas stores are converted into Korean won.
- Deal cards show the price without shipping and the shipping fee separately. The lowest price on a product page includes shipping, so the two numbers can differ by the shipping fee.
Lowest recorded price
- The lowest recorded price is the lowest price Dudeoji has recorded for this product.
- Comparison statistics and the lowest-price mark appear only after enough prices have been recorded.
- An unusually low price seen only once may have been misread, so we mark it as unconfirmed.
Usual price
- The usual price is what the product normally sells for. We take the lowest price of each day and use the middle value.
- We add the below-usual mark only when records span several days, and never on deals that have ended.
Unit price
- To compare packs of different sizes, such as 30 and 60 pieces, we convert prices to a price per 100 g, per 100 ml or per piece.
- If we cannot read the quantity with confidence, we do not show a unit price.
Grouping the same product
- Posts about the same product on different communities are grouped to build one price history.
- We group posts only when we are confident they are the same product, and keep posts selling several products separate.
- If a price is grouped under the wrong product, please use the report button on the product page.
Where the data comes from
- We collect public posts from hot deal communities and store sale pages. We do not collect anything that requires signing in.
- Every deal names the original community and links to the original post, and we do not copy post bodies.
- The communities we collect are listed in Korean hot deal sites.
What we cannot confirm
- Prices and stock reflect the moment a post was published, so sold-out or ended deals may show late.
- We do not check whether a coupon actually applies.
- We may misread a pack size or unit. When that is possible, we mark the price as unconfirmed or for reference.
