...complete the sale. When I first logged in at 10 sharp there were all kinds of seats available all throughout the stadium. I bought my 2 and went back in and thought about trying to buy 2 more, so I added 2 more to my cart and almost completed the sale, but figured it'd get caught eventually anyway so I just cancelled it.

But those 2 seats were in my shopping cart when I went back in later to look and see what was still available. I'd imagine a bunch of other people did similar things and when they didn't finish the sale the inventory popped back up.
