As for the service you received, I apologize. However, while you may think, "How can one little camera not fit on a truck," the fact is it very easily can't.
In order to protect small items like cameras and camcorders and mp3 players from damage and theft, when they are sent to stores, they are sent in locked bins instead of just loose on the truck. These bins are roughly the size of a "watermelon pen" you see in grocery stores. Black friday is the #1 selling day for cameras and camcorders, so these pens fill up quickly. Once you get one stacked on another, you've basically got something the size of two refrigerators taking up a lot of space on the truck.
The week after black friday is a very busy week for customer pickups, and sometimes the trucks can't fit everything. At my store, that's why every morning that week, we check open orders and call the customers whose items didn't make it on the truck. At the store level, we do not know until that morning what will be on the truck.
I'm surprised that you say the manager told you 10 days! No store ever has to wait more than four days for the next truck, even our smallest stores.
I would suggest, if you are still unhappy, to call 1-800-28-GREGG (1800-284-7344) and speak to one of our customer service staff.
