You wont find it on walmart website its not listed but its in stores i did same thing.

And the flukers WILL work but its like $20 and has no probe so why buy it?

If the acu rite is at home depot for $20 it comes with temp on the box, the prob, and humidity where the flukers cost $20-$25 and only has the temp of the box and humidity but no probe

Seems like a big waste of money to me

Check walmart (in store) ask where their therm/hygro meters are and i bet its there
