I am not super sure, but I would check the Walmart website, and if there is one, make sure it is near your location by typing in your zip code!
Yes they DO have portable air coolers besides the room size conditioners. One is about$30 by Mainstays in household area and the other is ASOTV at the front end of the store for $40. Both will cool near the unit and use distilled water and plug ins. Both are fairly quiet. Clean to use.
Yes they should have portable AC units they do have to be plugged into a power source though. Target has portable ACs as well.
