When you purchase products on DLsite, you can receive points based on the purchase total, and associated point return rate.
Those points can be used to purchase any item at the rate of 1 point = 1 Japanese yen.
You will receive these points when you leave a product rating within 90 days of purchasing the product.
The points are not received upon purchase.
Ratings can be left from [ Product Ratings / Reviews ] on My Page.
When you use points to purchase a product, point return is calculated using the purchase total minus points used. If products have different point return rates, point use will subtract from the total of the product(s) with the lowest return rate first.
Furthermore, when you purchase a product using a coupon, you will not receive points for that product.
Points also have an expiration date. Points will be lost 1 year after the date of last point use or acquisition.
You can confirm the expiration date for points from [ Point Inquiry / History ] on My Page.
