I was getting off the SkyTrain today, and I noticed this note stuck to the route map above the door. It simply says “Save $$, DealByDay.com“. I gather that it’s one of a bunch of these (slightly parasitical) daily deal site aggregators–another is OneSpout.
That’s pretty much the cheapest advertising I can imagine. The creator was so economic, he didn’t bother to write out the word “money”.

And it’s gotten him blog posts and links 🙂 Clever guy, someone should have a chat to him and if he knew what he was doing hire him.
