Advertisements I have been considering a Roku Smart Soundbar. I know that Wal-Mart carries a lower priced version, but I would prefer the version carried at Best Buy and Roku.com. As I looked at the Roku website, it appears that the Roku Smart Soundbar can only be purchased direct from them or Best Buy. How common are these type of agreements in consumer electronics? I am not against Best Buy, but I would like having the choice to buy from other retailers, if possible. Are these agreements typically for a fixed period of time or are they sometimes for the life of the product? And, I also realize that it is possible that there is not an exclusivity agreement in place, but I suspect that there may be since I don't see this offered anywhere else.
