Wow, I'm pretty sure I got very lucky just now. I signed up for the Stamps.com offer, only to get credit for it literally 10 seconds later. I didn't even have to download or install anything. From what I had read in this thread before, this offers took weeks, even months, to credit. Anyways, I probably still shouldn't have to download and install the program, right? And also, for the 4 week trial, when have people canceled? I was thinking after like 21 days maybe?
