In my opinion there is no such thing as a free lunch. As much as I hate prices rising I believe that it is important that you have a level of confidence that your supplier is in a position to provide whichever service you have bought.
I know that the statement is that all suppliers use the same pipes/wires/`phone lines, but in the same way that supplies were cut when the Russians raised prices to another ex-satelite country I feel the same could happen if there is a conflict between a `good payer` and one who provides for less. I`d like to think I`m wrong but .....
There is also the argument that with a limited resource, all prices will rise eventually anyway. You may gain a little in the short term but long term it will all even out.
Bit like the NHS vs. private medicine; if you want whistles and bells........... Not necessarily better treatment.
