It is! Every carrier increased rates in January, even for First Class mail in the USA - its even worse outside the USA. In all cases we are including a subsidy to keep those rates lower than the published rates to try to help out. As a small publisher we can only do so much though before subsidizing ends up sapping all of the funds. We have always delivered on all of our campaigns the past 7 years and want to continue doing so - so sadly, as postage increases, we must pass on this increase too.
