I will just add that those people who say "I will never shop there again" are, in my experience, largely pontificating and likely to go back on their word as soon as a deal is to be had.
The internet makes grandstanding over this sort of thing even easier...
I've lost count of how many times the 'what should I buy' threads end up with the OP stating something along the line of "I ended up buying from Harvey Norman / Noel Leeming / PB Tech / JB HiFi' even though I avoid them out of principle... but they were $43 cheaper and the other guys wouldn't match them".
Money talks, internet bull walks.
