The IT industry has to be tops when it comes to over packing.
One example I've come across many times is for software licenses. These are often just a single sheet of A4 paper with a license number or sometimes just a statement that the possession of said paper allows you to run the software.
The piece of A4 paper is usually sent , unfolded in a cardboard box. If you're installing a number of systems, it's not unusual to get a pallet load of boxes containing nothing but these licences plus of course the larger boxes needed to hold all the smaller boxes.
To top it off, there's usually some proud boast from the company to the fact that they're really green and care for the environment - except for the bit that contains (or used to contain) trees.
Here's a good example of overpacking from HP.
Don't get me started on software licences.
When you buy a piece of software how many shops let you read the licence agreement beforehand? None that I know of.
There are lots of shops which will also refuse to accept refunds for software, especially if the box has been opened, in case people buy it, pirate it and return it. So what the hell is one supposed to do if they buy some software, open the box, read the licence agreement but decide they disagree with it?
This sort of business practise encourages piracy, for example: if a teenager buys a game which they play for five minutes and they discover it's crap, then they discover they can't get a refund, they'll be more inclined to just download it from a warez site in future, rather than buying it.
Then there's the fact that licence agreements are too bloody long and a layperson would require a lawyer to fully understand them and some contain clauses which are illegal in some jurisdictions so parts won't apply to everyone, everywhere.
Perhaps there should be a maximum number of words for a licence agreement aimed at home users, who should have the option of reading it, before they hand over any money?
There's a very funny cartoon on the Internet somewhere about a woman who buys a piece of software, reads the licence agreement which asks her to do all sorts of silly things such as flash her tits to the computer before she can legally use the software but I can't find it.
