I don't know, I don't think it'd be as much as 4 - 7 days before Christmas. Most people know that it's too late to order from Amazon or any other online-only store by the night of Dec. 23. It's probably more money than they'd lose normally, but maybe not that significant?
I have no data to back that up, it's pure speculation.
