Cyber Monday sales lack the punch of the in person black Friday sales because on those ones stores can count on people buying random other stuff.

(While waiting in line for a bf xbox deal many years ago at Walmart, we were queued up in a line snaking through the pet section and one of the people in line behind me put enough random ceramic dog bowls / toys / other weird stuff that wasn't on sale on their cart to cover any money walmart was losing on the xboxes)
