Why are Macintosh users compelled to subscribe to a service just to buy postage? If you're running a business that requires significant monthly mailing then obviously this is a no brainer. But Windows users seem to have options that allow them to buy postage on an as-needed basis, and directly from the postal service, with no subscriptions... Why don't Mac users have these options? I have a UPS account, and can pay on an as-needed basis, with no monthly subscription? Don't get me wrong, I see Endicia's service as a good one, just not what I need or want, or am willing to pay for.
