question about paperback releases

I am kind of a noob with the comic area of transformers, but I was wondering do the trade paperbacks typically get reprinted after they have sold out? I am talking about infiltration for the most part, but also all hail megatron vol. 1 etc...
Most places online say they are sold out, and only have used copies at twice the price or more. So do they generally do one run of the prints or will they be releasing more copies?
thanks
