Already happening to an extent over here....
Look at any bottle-o that belongs to a supermarket chain. At my local Vintage Cellars they have their own brand of Maxx Dry which is quite cheap compared to the TED they sit it next to on the shelf. They even had a special running where you could get a 6pack of each for $20 for a while. Which means your average TED drinker would walk in and grab his/her usual 6pk, which would cost $16 and figure "Hell, another 6pk for $4, sure"......
Next time they come in they notice the price difference and figure it tasted almost the same anyway, so they grab the MAXX instead........
