The thing that a lot of people don't understand is that when you buy something, you agree to the seller's terms and conditions. Most of the time, these are not geared to be in your favor in any way. It really is sad that is the way it is, but with the way it is now, if they farted in the box, and you opened it, you could sue them for discomfort.
One way to get around this, is to actually read the terms and conditions for that company, and call them if you have any issues with said terms and conditions instead of just clicking the box when you make an order. The only reason I say it like this, is I was that guy that would just click the box, and be upset later. Now with my current job, terms and conditions de-rail a lot of work and are held up in legal review for months. Now I review everything that I buy except airline tickets, because no matter what you do with airlines, you will be in the wrong. Always avoid a company that has something like, "terms and conditions can be changed at anytime persistent to the seller's needs." Translates into yes, we will screw your order up, and we will not be responsible.
