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.
Compact discs or CDs were developed in 1979 as a direct successor due to the declining popularity of vinyl records. CDs originally had enough space to store 60 minutes of music. Sony quickly developed the technology extending capacity to 74 minutes and adding wider appeal to the new media format. At the turn of the 80s and 90s CDs drove the price of vinyl down. Compact discs now store 80 minutes with a capacity of 700 MB, and are also a popular medium for storing computer data.
