It depends on the size but if I'm not mistaken the smallest ones which fit 2-3 loads are 1.75. The big ones...they are 3.50 or 3.75 and they dry 8 loads. And they all work. They are always really hot.
The small ones are $1.75 for 25 or 30 minutes (I can't remember which). You can select your desired heat level (high, medium).
