Since they don't ship on Saturday and Sunday but people still order, on Monday when they start work, they have a whole load of orders to process from the weekend, and since you ordered on Sunday that means that yours will probably be a little later than the rest since they process the oldest orders first, like something that was ordered Saturday morning. Don't worry about it, as long as your payment is good they will get to it. I've ordered from newegg before also, they are reliable.
