I understand that PetCo is being reasonable and reserves the right to cancel the orders, except for two majorly glaring problems. One, they found out pretty quickly that there was an error, some time around 8PM on 6/23 people were saying how they had called Petco and were being told they were aware of the mistake, yet it hung around on the website for AT LEAST 24 hours longer, and people were still able to successfully place orders at that price. Two, this was a MAJOR sale weekend for Petco. They do this sale every year about this time, so the only reason 10k of these things were ordered was because they were advertising a sale on the entire site and traffic volume was already way above normal. If somebody missed a digit on an item next weekend, I'd be amazed if half as many got sold in the same time frame. Now, even if they have a disclaimer you can find if you go hunting on their website, they've gotten a lot of people excited about getting an awesome deal. I, for one, am not going to get angry if I don't get the cages I ordered, because I recognized it as a mistake the moment I saw it, but thought I'd take a chance anyway. Not everyone else who ordered knew that it was priced in error, and they'll very likely take a hit by way of angry customers as a result. Will they lose as much that way as they would have by actually filling the orders? There's no telling.
