Doujin sales may look irregular, but several recurring patterns are useful when reading the current price.
Common types of sale
Store-wide campaigns
DLsite runs limited campaigns around seasonal events and holiday periods. The number of eligible works, discount rates, and exact dates vary, so a past campaign does not guarantee that the same price will return.
Circle-set discounts
A circle may discount older works around a new release or apply a temporary reduction to a series. These schedules are set by the seller and can be difficult to predict.
Coupons
A coupon can reduce the checkout price without changing the listed sale price. R18Deals records the price shown when data is collected; coupon availability and eligibility must be checked on DLsite.
What to check before buying
- Observed lowest price: a comparison with the lowest price recorded by this site, not a guarantee about all historical prices.
- Sale deadline: when DLsite publishes an end time, it can help distinguish a limited sale from an ongoing price.
- Current store page: confirm the final price, currency display, coupons, and availability before purchasing.
