While I haven't tried this service and thus cannot vouch for it, I can say that:<p><i>"I love your business model!"</i><p>It's simple, it provides a lot of value for a little bit of money (yet still allows you, the owner, to make a tiny profit on each transaction), and it doesn't require a complex database driven website...<p>Also, I'm guessing (but not knowing!) -- that a business like this could be started for $50 or less... the only thing you'd really need is a good enough postcard printer (OK, so maybe a bit more than $50 if you include that), some cardstock, and the willingness to make a trip to the post office (or local mail drop-off point) every day (or when orders were received...)<p>Again, I reiterate, <i>"I love your business model!"</i><p>The only real thing that a business of this sort would need then is some online advertising...<p>Google ads would be too expensive relative to the cost to acquire new customers -- so you'd have to advertise via single links posted here and there on public forums...<p>Well, I upvoted you and favorited you here on HN -- which might generate a teeny tiny bit more traffic for you -- or so I hope!<p>Wishing you and your business well, whoever you are!
