HDMI-to-RCA cables are available to be purchased from Wal-Mart. However, availability of the cables depend on the particular Wal-Mart location; some locations may carry them in stock onsite, while other consumers will have to purchase the converter cables online. Online purchases can either be delivered to the customer's home or picked up at a local Wal-Mart store.
The HDMI-to-RCA cables are available in the electronic section on the Wal-Mart website. To find the cables, navigate the menu section on the left side. Locate the "TV & Video" section, then click on the "TV Accessories" title. The next page will lead into Digital Converters, which has a section specifically for HDMI-to-RCA wires, converters or other accessories.
