I would go online. walmarts prices (canadian prices) range from $15 for analog to $30-$50 for digital. you might find a better price at a car shop... like Canadian Tire... ? not sure what the US equivalent would be. They sell cookware, Car radios, Tires, bikes, Gardening, hunting, Tools, vacuums, Light fixtures... paint. still $15 for a digital hygrometer, but better price than walmart.Analog was all they had. I can try Walmart or Amazon, I guess
These are the ones I prefer:

I've found the temperature readings to be quite accurate. The RH I would double check what it's reading at of the 3 I had not one read the same as the others. BUT if you do a salt test with them you can mark what the variations are and then they are accurate with a little math.
