Same pattern. Ordered cheap Digital Elph. VIP called and asked which aftermarket battery we wanted--said that battery that comes with camera is good for "15 minutes" (and later translated that into "15 photos"). I'm sure Canon would be happy to hear this. After my wife declined, they pushed hard for extended warranty with similarly dire predictions. My wife also declined.
Within minutes after getting off the phone, we received an email saying "The item you purchased is currently experiencing a back-order based on the latest logistics 4-6 weeks is the time frame for delivery." Never mentioned, obviously, on the phone.
