Deal weeks - Detectors

Discounts, codes, and cashbacks are limited-time promotions in which you can save a lot of money. If an item is on sale, you will see the new price right next to the old one. If a discount code applies to a product, you will find it in the category listing above the product price or in the product details below the image gallery. You must then enter the discount code in the "Use discount coupon" field before submitting your order. Items with a cashback option are also marked in the same way. If certain conditions are met after purchasing these products (e.g. registration of the goods on the manufacturer's website), you will receive part of the total price back. You can find out all the terms of the specific cashback policy in the product details.
