Criteria will objectively be whatever Company has the next speaker featured as BestBuy's "Deal of the Day" (let me know if it uses your location, and isn't universal and I'll cancel the market, below is what I see 10/18/2023 ~10AM EST). Bonus deals of the day do not count.

The item featured as deal of the day must be used for the main purpose of being a speaker (not just contains a speaker). Market will close and resolve once there is a day where a speaker is featured.

As noted in the comments, there have been days where I have not checked this best buy page, so feel free to bring it to my attention if a speaker is featured.
