I understand exactly what you are refering to and yes in some ways you are correct but since i have turned all my betting activity to the internet and away from tabs i no longer use my tab accounts unless i am after an exotic bet not offered.

The online services of other sites a far better than the tab would ever offer so why use the tab, IMO there are two kinds of punters, online punters and offlines punters..

To use the situation you put forward with the supermarkest there used to be good competition from the smaller chain of markets like supervalue, foodland and what ever else your state has over here in the west it is "Action" these stores have been losing out to the big boys for a long time because of the market share so instead of trying to compeat in there own market they joined together to create IGA this is nation wide and alowes them to buy at a cheaper price to offer a cheaper price.

The tabs are trying to buy each other out right now and when somone owns them all they will relise it is in the best interest to make one Tab it is not a matter of IF it is just a Matter of WHEN.
