I "lost" a SatNav earlier today despite clicking the millisecond it appeared. I joined the waitlist at 500+. Went upstairs to change DS's nappy about 45 minutes later and came down to find it had been in my basket briefly but had then left.
That was bad enough, but it gets worse. I rejoined the waitlist. The deal expired a few hours later so I assumed that was that, especially as it said 100% claimed. At some point this afternoon, about 3-5 hours or so after it was listed (can't remember exactly) I went back to the Amazon window and saw the same thing had happened again. FML. Evidently the waitlist persists even though the item has expired.
So people on waitlists.. just keep waiting and checking your Amazon window.
