Mk3 thermistor

So i bought a mk3 heatbed from amazon, thought it came with the thermistor but i must have been mistaken. Where the heck can i find one? All the radio shacks in my area have all closed. Any other brick and mortar stores that might carry them?

Not in my area. Online only

Fry’s or Microcenter should have them.

Ryan do you have them seperately? I need a few other things if you do.
