Do you think that the web store should be responsible to its mistake?

Online transactions do not have such pro-formas, contracts, etc., for such placed orders so we cannot say that the famous web store you are refering here will be in a full responsibilty for such complains.

Legally speaking, the web store has the right to cancel the orders. The price of product it shows in its website could be defined as invitation to offer. The conduct of placing an order by consumer is an offer. It's the web store who decides whether to accept the offer or not. So such cancellations don't violate the law. But it's obvious that the conduct of web store will inevitably damage the reputation of it. As a web store who wish to make its brand famous, it had better continue the placed orders.

I thinkthe store should honour it, and look closer the next rime to keep it from happening again.

I have heard of companies online doing this if a price is wrong. As such errors spread like wild fire on the internet and people knowingly share and take advantage of the error. I don't know what laws are the same online as they are with standing stores.

Well, for some reason this didn't post. I will try again. I think I know what this is about. I don't think it was right of this company to cancel all the orders for this product. It just shows me that all they care about is the bottom line.

I have also experienced similar thing with a book shopping site. I ordered a book for the price, and they were not shipping it to me for more than one week, after that they contacted me via phone and said that: the price of the book has increased, so we will ship you only, if your are willing to pay the extra amount. I felt sad and angry and i Canceled the order. I think it is the site responsible for these kind of issues. If they have not offered the less price, the buyer, would have bought it from some other site. It is the low price that attracted buyer to the particular site, so they should give it for the offered price.
