Batteries and Coconut Oil

I find myself glancing at my wall-clock for the time of day and it never changes because the clock needs a new battery.  I reach for my mouse to control the computer cursor and it escapes my grasp because I moved it out of reach.  It too needs new batteries.  I have a pile of AAA batteries but both devices require AA batteries; I know just where to get them, the Dollar Tree.  It is near Walmart,  where I purchase my coconut oil.  So, I will go for a ride this afternoon.
