There's a lot of hoo'ing and indeed haa'ing about the Distance Selling Act, it came up recently in the LCD/DLP Proj Forum. Allow me to play devils advocate for a second, this isn't directed at anyone and is only presented in the interests of balancing the discussion.
How many of us here would be happy if we paid full whack for something then when it was delivered it became obvious that it had been opened, unpacked, used, the manual had been pawed over etc.? I'm sure I'd feel pretty hacked off, I would wonder what was up with it and why I hadn't got it cheaper. Wouldn't you?
Soooo.... what exactly are the retailers supposed to do with all this stuff that's been opened, tried out and people have decided against and returned? Should they sell it cheaper? Why? It's the customer that's changed their mind.
That's why the distance selling laws (as I understand them) specify that something must be returned unused and "as new" (i.e. unopened).
I do sympathise with people who consider sending something back when it isn't as good as they hoped, I've been there myself, but I don't think the Distance Selling Act provides you with much help.
I'm slowly learning that buying on-line is ok when you know the product you're buying will definetly do what you want, will look/sound good in your system, ideally you'll have already tried out a mate's or something. But if the first time you try it is when you've paid your hard earned and it turns up - you're heading for problems.
Again these are just my thoughts and I'm not having a go at anyone.
If only dealers with the ability for home demos etc. were a bit cheaper/more common.
P.S. I'm not a retailer or connected with one in any way.
