Came across this earlier. Argos in UK are now selling electronic cigarettes. Does not seem to be available on Argos Ireland website yet. I am not familiar with the actual brand / model they are selling, but either way this move, I think should be seen as a positive step, as it helps make electronic cigarettes and vaping more mainstream.
The brand / model that Argos are selling is called the Vapestick, with their Vapestick Classic looking very similar to the 510 Electroinc Cigarette Starter Kit that we sell at EZ Smoke, but more expensive!
