> Why two free stamps per month? I figured that you need to be able to send yourself at least one sample -- it takes one stamp if you live in the US and two stamps if you're anywhere else on the planet. > If someone uses your free service for three months, or six, or twelve, what are the chances that they will upgrade to a paid service? Ask me again in 3, 6 and 12 months. :) > Why would this be more profitable than a plain pay-as-you-go plan with no free stamps, or one or two initial trial stamps? I originally had no free stamps included in the pay as you go plan. This idea of including a few free stamps started up just a few weeks ago so I don't have any long term data. The theory here is that I "hook" you buy giving you an easy way to send your first letters... then you'll (hopefully) see the value in upgrading. > If I choose to sign up with one of your monthly plans, will you offer me a refund of my unused credit if I decide not to use it? Technically, no (it's in the TOS, etc). (Though, I'd probably refund the money if someone asked for it. I'd rather keep some good karma going...) When you pay your phone company (or 37signals, or anyone else) for a full month and then decide to quit, I doubt any of them will easily give you a refund. :)
