I just renewed Maximum PC (non-CD edition) for another two years for US$24.95 via its publisher. However, I’ve noticed other online magazine services, including Amazon.com, have it a lot cheaper. Even for the price that I paid for, I still feel that it is worth every penny. But I do wonder why the huge price difference. I don't think that it is because of the introductory offers, since the renewals are also cheaper via the said services.

This also applies to PC Gamer as well, which I subscribe to the CD edition. Therefore, in the future, I am considering of renewing both my subscriptions via online magazine services instead of directly from the magazine publishers. So, what do you guys/gals think?
