Consumers can buy Adobe CS5 software from sites such as Amazon and eBay. It can also be purchased directly from Adobe.
When purchasing Adobe CS5 software, users will obtain a unique serial number or key with which to register their product. Without this number, the software cannot be fully installed or used. New versions of Adobe Creative Suite are also available. The price and inventory when it comes to the software will vary depending on the seller. Since the CS5 version is no longer produced as of 2015, it can be more costly than some of the newer versions on the market.
