I've used several coupon websites in the past, and 12COUPON.DE is just an average one. While their coupons are valid and do provide some discounts, I found the website layout to be a bit confusing. It took me some time to figure out how to search for specific coupons. Additionally, the lack of a mobile app makes it less convenient to use. However, the overall experience was decent, and I did manage to save some money with their coupons.
